Domain name levels. What is Domain Level? Examples of domain names Bestof service - for socially significant projects
Our studio is actively working with the segment "Automobiles", we even have a special project Car-Liner.ru for this category of clients, and when analyzing the situation for each automaker, we often find that the owner of a brand of a car brand often uses a scheme when the sites of dealers of this brand are built on a 3rd-level domain, where the main domain is the automaker's domain.
Such automakers proceed from logic:
- Car dealer website on a 3rd level domain promotes the car manufacturer's website
- It is easier for us (the car manufacturer) to pay once for the development of the design and functionality of the site and distribute this site to dealers for free
- The whole system works like a clock
Statement one: the car dealer website on the 3rd level domain promotes the car manufacturer's website - this statement is fundamentally wrong! A site on a 3-level domain not only does not help the presence of dealer sites and the distributor's site in the search results, but also has an extremely negative effect on the promotion of sites for search queries! This means that it pulls the entire dealer network down.
Let's take a look at the disadvantages of 3rd level domains:
- Some search engines ignore such domains altogether, which means that it will be much more difficult to find your site on the Internet.
- Your site's domain name is lengthening.
- Domain of the 3rd level, as a rule, is rigidly tied to some host and changing it means changing the domain.
- Having spent a lot of effort or money to create a site, choosing a unique, memorable domain for it, you will negate most of your efforts by placing the resource in the zone of non-commercial (3-level) hosting, because such a site loses its uniqueness. And this is of great importance, especially if your site is a company doing serious business.
- In addition, the use of non-commercial hosting raises doubts about the solvency of your company: the company simply cannot allocate funds for registering an individual second-level domain.
Second statement: it is easier for us (the car manufacturer) to pay once for the design and common functionality and then distribute sites to dealers for free - such a statement of the question is quite common, but unfortunately, such dealer networks often lose weight and cannot understand in any way why dealers ignore the promotion and promotion of their sites, which the automaker has kindly provided to the dealer?
And really, why?
And all because in 98% of cases such a site cannot be configured for SEO, it is impossible to make the necessary settings on such a site and ... look at point one - a site on a third-level domain! With all the ensuing consequences. We've had to talk to dealership executives and marketers who are forced to have these sites. Do you know what they say with one voice? "For us, dealers, such sites do not add sales. We must have them - that means we must, and we make sales on our advanced and pumped sites!"
Statement three: The whole system works like a clock - it is difficult to argue with this statement, only this clock moves in the opposite direction and the precious time required for site promotion is melting away.
Those who are familiar with the basics of SEO site promotion are familiar with the fact that this is the very SEO site promotion, due to the fact that the leading search engines Yandex and Google are constantly changing their requirements for sites and ranking algorithms in search results, it becomes more complicated every year is getting more expensive. And what could have been promoted in the SERP yesterday is no longer possible to promote today and tomorrow.
So what do you do? Stubbornly move in a dead-end direction, create and maintain sites on third-level domains?
There is a solution! At the very beginning of our article, I wrote about our special project Car-Liner.ru. It was created specifically for the management of the dealer network and eliminates all of the above problems. Car-Liner.ru is a turnkey solution that can be applied to any car manufacturer and its dealers.
Car-Liner.ru includes everything a car manufacturer needs to manage its dealer network:
- Corporate portal- employees of the car dealership on the one hand, and employees of dealerships, on the other hand, are connected to it to exchange files and messages.
- News management- all the news that the distributor puts on his website are automatically posted on the dealer's websites, which makes the dealer's websites manageable in the field of the information policy of the automobile brand
- Lineup management- all changes in the model range are automatically posted on dealer sites, which makes dealer sites manageable in the field of organizing sales of an automobile brand
- Test drive application- the automaker sees and can control all test drive applications that potential buyers fill out on dealer sites
- Press portal(function in development) is a corporate portal for interaction with the media - a powerful tool for interaction between the automaker and various media - newspapers, Russian magazines, Internet portals, radio and television, independent journalists and bloggers.
- Stock cars(function in development) - stock management, car ordering by dealers.
Adding a subdomain / subdomain.
How to add a domain and bind it to Plesk Panel is described
Unlike the main domain, subdomains are added not in the personal account, but immediately in the panel Plesk.
Now let's consider 3 options for creating a subdomain:
1) Adding a subdomain to the main domain webspace.
2) Adding a subdomain as a separate webspace.
3) Adding a subdomain as a main domain in an already existing webspace.
Option 1.
Adding a subdomain to the main domain webspace.
1)
Near the domain to which we want to add a subdomain, click " Add subdomain
".
3) Done! Now we expect 15 minutes and the subdomain will become available on the network.
Option 2.
Adding a subdomain as a separate webspace.
1. Create a webspace with a domain poddomen.test.ltd:
Plesk > "Webspaces" > "Add webspace " .
2. Go to the domain web space created by us poddomen.test.ltd.
3. Go to the section "Websites and Domains" > "DNS settings" and click on the button "Disable".
4. Go to the web space of the main domain - test.ltd.
5. Go to the section "Websites and Domains" > "DNS settings".
test.ltd... Click on "Add a note" ... In field "Record type" choose "A", in field "domain name" indicate " poddomen", in field "IP address" poddomen.test.ltd "domain name" www. poddomen
Option 3.
Adding a subdomain as a main domain in an already existing webspace.
1. In the existing web space, in the section "Websites and Domains" , click on the crop " Add new domain " .
2. In the field "domain name" indicate our domain poddomen.test.ltd.
3. Go to the section "Websites and Domains" > "DNS settings" and click on the button "Disable".
4. Go to the domain webspace test.ltd.
5. Go to the section "Websites and Domains" > "DNS settings" .
6. The DNS setting for the domain zone will open test.ltd... Click on "Add a note" ... In field "Record type" choose "A", in field "domain name" indicate " poddomen", in field "IP address" specify the IP address of your server. Further, if we need to refer to the domain using the www prefix (www. poddomen.test.ltd), then add an additional record in the same way, specifying in the field "domain name" www. poddomen... Next, we save the changes and the DNS record will be successfully updated on the primary DNS servers.
A third-level domain is an independent site that is located on a second-level domain and is tied to it. That is, it is a subdomain of the main resource. Domains of the third level are blogs and sites on free hosting, the name of which has the following format: xxx.xxx.ru or xxx.xxx.com and others. The first word in this construction is the name that was invented by the user, and the second word after the dot is of the senior, second level. The subdomain is located on it. For example: poddomen.blogspot.com.
It should be remembered that by registering third-level resources on free hosting, the user does not receive absolutely no rights to them. In this situation, the owner of the main resource is the copyright holder.
Owners of second-level resources can make a junior resource - a third-level domain, if there are no registrar restrictions on this operation. Domains of the fourth (xxx.xxx.xxx.org) and lower levels can be created in the same way. However, this depth is rarely required.
A serious drawback is that the average third-level domain name is not very popular among the robots of some search engines. For some reason, subdomains are sometimes indexed by them very reluctantly and poorly retained in the index. However, such problems do not always arise.
A third-level domain is most often used when it makes no sense for a new site to acquire an independent second-level resource. It is quite possible to perfectly place a selling page or a subscription page on a subdomain. That is, to make a website with several pages at no cost. If you plan to build a large site based on a subdomain, you can install any CMS on it. Also, the owner of the second-level resource can, if desired, provide subdomains for creating blogs and sites. A lower-level resource can be used as offloading for a crowded primary site.
Before creating a third-level domain, you should first make sure that the hosting has support for subdomains and the ability to create them is included in the cost of services. This information can be viewed in the hosting control panel. If the service is not provided, you need to request it from the hoster. It can be either paid or free. Each hosting has its own methods and capabilities for creating subdomains.
On some hosting services, to create a simple site on a subdomain, it is enough to create another directory with a name like poddomen.yoursite.ru in the main folder in which the directory with the main site is located. When creating a subdomain, you need to take into account that it must have an index.htm file or the site will not open. CMS systems are installed in the same way as on the main site, however, a separate MySQL database is required for the subdomain.
On some hosting, a third-level domain cannot be created by yourself. To do this, you need to leave an application in your personal account indicating the desired name of the 3rd level site. Within usually no more than a day, the administration will create the desired resource. After that, you need to enter the addresses of the DNS servers and fill the resource with information. For many hosters, the ability to create resources of lower levels is initially included in the control panel, but on some resources of the third level it is generally prohibited. The way out of this situation can be the creation of site subdirectories.
What is a domain? Almost every novice Internet user asks himself this question. Without going into details, the answer is pretty simple. Domain is the name of a site on the network, unique and unparalleled. You can view the domain on which the page you are currently viewing is located in the address bar of your browser .. Everything after these letters is the path to this article.
In fact, site addresses have numerical values that are very difficult for users to remember. But now that the domain name system has been developed, each site creator can assign it an easily pronounced and memorable name, which makes navigation on the Internet more convenient.
Domains are usually divided into several levels. Each level is determined by how many dot-separated parts are in the name. For example, a first-level domain is nothing more than a zone on the Internet. Websites on domains of the 1st level are not located.
Examples of
- .ru - Russian
- .ua - Ukrainian
- .com - Commercial
- .org - Non-profit organizations
- .edu - Educational Resources
- .gov - Government
- Other options (more than a few dozen)
Second-level domain - designates the name of a resource within one of the domain zones. For example, our Businesslike forum is now located on a second-level domain, where Businesslike is the name of the site, and.ru is the zone in which it is located.
Domain of the third level - determined by the name of a resource within a domain of the second level. Name. Second level name. Domain zone. Typically, 3rd level domains are completely free. Take, for example, Ucoz, a site builder known to many webmasters, which gives clients domain names like site.ucoz.ru; site.at.ua and the like.
A fourth-level domain is a rare occurrence on the Internet. They are built according to absolutely the same principle as the previous levels of domains, only the name becomes even longer. For example: video.site.hosting.ru.
Which domain name to choose: 2nd or 3rd level
Now that you have got an idea of what the second and third level are, you probably want to know which one is best for your future site. Let's try to figure it out.
Example request:
Lang: ru
request: order
operation: create
login: 123 / NIC-REG / ADM
password: qwerty
subject-contract: 3457 / NIC-D
service: domain
action: new
domain: test.ru
phone: +7 495 1234567
fax-no: +7 495 1234568
nserver: ns2.site
nserver: ns1.site
An example of a request for a geodomain:
Lang: ru
request: order
operation: create
login: 123 / NIC-REG / ADM
password: qwerty
subject-contract: 3457 / NIC-D
request-id: [email protected] website
service: domain
action: new
domain: test.msk.ru
descr: Domain for test purpose
e-mail: [email protected]
phone: +7 495 1234567
fax-no: +7 495 1234568
nserver: ns2.site
nserver: ns1.site
In the request header, you must specify the values request: order and operation: create (see).
The order-item blocks follow the request header. The number of these blocks is unlimited, i.e. in one request, you can order an arbitrary number of services (including those not related to each other). Each block begins with a heading indicated in square brackets on a separate line.
The block consists of the following fields:
| Field | Field value |
|---|---|
| service | The type of service ordered. In this case, you must specify a fixed value - domain (see). Required field. One line field. |
| template | Template of the ordered service. You must specify a value client_ru - for .RU, .SU or third-level domains; domain_rf - for.РФ (cm. ). Optional field. One line field. |
| action | Order type. To order a new service, you must specify the value new in this field. Optional field (by default its value is new). One line field. |
| domain | The name of the domain to be registered along with the zone. The domain name in the national language must be indicated as "XN - ***". Required field. One line field. |
| descr | Domain description in free text format in English. Displayed through. The field can contain Latin letters, numbers, punctuation marks and spaces. The maximum field size is 300 characters. Optional field. Multi-line field. |
| e-mail phone fax-no |
Contact information for display via Whois service. The fields can be empty. The specified data will be displayed in the Whois service responses only if the phone, e-mail and fax-no fields for the domain are filled in. Otherwise, the data from the questionnaire will be displayed. |
| nserver | Domain DNS servers in the format servername - space - IP addresses separated by commas. Specifying the IP address (s) is required if the DNS server name contains the domain to be registered. In all other cases, specifying the name of the DNS server is sufficient. Optional field (but if filled in, at least two DNS servers located in different class C networks must be specified). Multi-line field. |
| check-ns | The flag that controls the launch of testing DNS servers when registering the .RU, .РФ and SU domains or when sending an UPDATE order to change the list of DNS servers for the registered domain. ON - initiate the standard DNS server testing procedure, OFF - do not carry out the standard DNS server testing procedure. An optional one-line field (by default, it is ON). |
The order of fields in the request is arbitrary within each block. Multi-line fields are written in several lines, with the field name and separator (colon) at the beginning of each line. No repetition is allowed for single-line fields. Optional fields can either be missing in the block, or their value can be empty (consisting of whitespace characters).
Sample answer:
State: 200 OK
request-id: [email protected] website
order_id: 4515
The response contains the header (see) and the response body, which is separated from the header by an empty line.
In case of successful execution of the request (code 200), the body of the response contains one field - order_id, which indicates the identifier of the accepted order.
Note: For this type of request, the code 200 only means that the request does not contain syntax errors and is accepted for processing. The specified code does not mean that the order was completed with a successful result. The order_id reported in the response can be used to query for. In response to such requests, accurate information is provided about the status of the order: completed (successfully or unsuccessfully), in processing, etc.
If errors are found in the request form, a response with a 402 code is returned, and the response body contains an errors block with a description of errors in the language specified in the request in the lang field.
