Domain names in recent years so firmly in our lives that we perceive them as well as a phone number or a mailbox.With this name, you can go to the site you want, and so we are interested to know all the information or perform the desired action.This is the same string, you can use to find what we need.However, few people know how to operate the domains and what they are.
What is a domain?
domain is the transformation of IP-address of the server that contains a resource that we're looking for, driving in a domain name.In fact, in order not to remember the address like 192.193.0.0, and were launched addresses the type domen.com.With their help, you agree to use the Internet made it much easier and more convenient.At the same time, many even managed to build a business that is selling beautiful and easy to remember domain name.After all, with such a name is easier to remember the clients site, and advertising a similar name can be mentioned.
domain hierarchy
Domain names are constructed in the hierarchy, the levels are divided into specific domains.There may be as many, because the name of the administrator is able to create their own so-called sub-domains - lower on the hierarchy of domains such as poddomen.domen.ru.Next will be a subdomain of this kind: poddomen.poddomen.domen.ru and so on.Thus, a lower-level domains.
mentioning the name of the top-level domain, it should be noted that it is, roughly speaking, its ending.For example, there is the top level domain, it is called first.This zone .com, .net, .ru or .club, .travel and others.Ordinary users can only order the registration in these areas, and to create their own zone can only organization that manages domain names ICANN.
Second-level domains
second-level domain - a name consisting of two words separated by dots.For example, it is a site or domen.com domen.travel.This name is as short as possible (in the hierarchy), and consequently, most prestigious.
As a rule, second level domain names in all the zones are paid.But there are exceptions to all rules, including this.Such areas as .tk, .ml, .cf and .ga, can be registered for free.For example, to seize the name domen.tk everyone can without making any registration fee (of course, if that name is available).Free second level domain different from the paid (for example, .com) that among the latter is much less spam and hacker sites offering online fraud.This means that search engines, and users will still give preference to sites that have a paid second-level domain.Especially since the registration of the same .com is not too expensive - 15-20 dollars.This sum is paid once for the entire year.Everyone who runs his site is able to find so much money.And it's worth it, because registering a similar name, the user will not experience that his free second-level domain can close, "hijack" and carry out other illegal activities.For the vast majority of Internet projects is extremely important.
difference between one level domains
probably many times each user is faced with sites in various domain zones.Samih zones, to be honest, a few hundred.This global domains like .com, .net, .info;regional (assigned to a particular country) .us, .it, .fr;and a set of thematic domains.Recently, by the way, they became much more.These are areas, like .aero, .travel, .apple, .club and many others.
If we talk about the difference between all these areas, it should first be noted visual effect, which carries the domain."Yandex", for example, was originally located on the .ru, then started their "mirrors" in all other global regions.This allows not only to protect the brand (in fact, driving the address in any zone, the user is taken to a single search portal), but also to make the site theme, divide it according to the area in which it will claim.For example, Ukrainian domain "Yandex" is the Ukrainian version of the site (yandex.ua);Belarus - yandex.by on and so forth.
Choosing the top level domain for your site, do not forget about the subject site.Accordingly, the domain is selected in accordance with it.For example, the address of the club is perfect area .club, and addresses for airlines often use zone .aero.
Why create subdomains?
So, a logical question arises: if the top level domain - is, roughly speaking, "good", then why do we need subdomains - names in the hierarchy are an order of magnitude below?It is logical that the names of the sites like poddomen.domen.ru stored worse.
Yes, it is.Indeed, remember that name on the order more difficult than just domen.ru.However, that does not stop doing some projects on subdomains.For example, an online store which sells different categories of products, quite appropriate to establish the names kraska.magazin.ru, plitka.magazin.ru.Thus, the buyer will be easier to navigate, and the reception - easier to share certain categories of goods.
In addition, the existence of subdomains makes life easier for webmasters who are engaged in the promotion of sites.For example, in the case of increasing the number of links to a subdomain of this reference weight (which, incidentally, are very fond of the search engines) and transferred to the base name.And this is obviously very beneficial in terms of promotion costs.
Where to find the cheapest domain?
The question of where to find and register a top level domain is cheaper there, many webmasters.This is true especially for those who intend to run multiple projects and for this reason, of course, he wants to save on total cost of domain names.This can be achieved only in two ways: the registration of registrars offering lower prices, or the wholesale registration.There are companies that register names at a lower cost.
As a rule, prices are jumping, and, therefore, these lists are constantly updated.Lead them to different bloggers and news domain-topic.With regard to the registration of wholesale, it is recommended to do so from reliable, older companies that are present on the market for at least ten years.So you get not only the good price, but a guarantee that all domains are, simply put, is in good hands.
How does configuring the domain?
Setting the domain name - the final stage, which takes place every webmaster who runs the site.It's simple: just need to specify the NS-record their host (usually a two servers that look like ns1.domen.com and ns2.domen.com).They should be put into the DVR.
addition to hosting side also needs to bind to a registered domain.This is done in the control panel order by simply prescribing name.Then you need to wait a few hours to a couple of days to write to the administrator of the domain zone update and a domain is visible in the browser of visitors.
