The DNS server (Domain Name System) is a service whose main function is to translate a domain name into an IP address. Basically, the DNS server acts like a directory that a computer consults when accessing another computer over a network. In other words, the DNS server is this service which makes it possible to associate a website (or a connected computer or a server) with an IP address, as a telephone directory makes it possible to associate a telephone number with a subscriber name.
Designed in 1983 by Jon Postel and Paul Mockapetris, DNS is therefore essential today in the world of web browsing. Each Internet service provider has its own DNS servers, with IP addresses that often take the form of a succession of numbers of digits (194.158.122.10 for example).
The registration of a domain name in Pakistan (of the “dmtwebhosting.com” type) is made with a ” registrar “, an intermediary organization between the applicants (or holders) of names of domain, and ICANN (Internet Corporation for Assigned Names and Numbers), a non-profit corporation responsible for the allocation of IP addresses around the world through the domain name system.
“Name resolution”
The Domain Name System was therefore set up to identify the different websites or domain registration in Pakistan in a simpler way: it is a system for “translating” IP addresses, addresses uniquely assigned to each machine connected to the Internet. (IP addresses are somewhat analogous to telephone numbers). The translation operation is called “resolution of the (domain) name” and must be perfectly understood (just as a telephone number must lead to the establishment of good communication). It is ICANN’s role to ensure that name resolution goes smoothly.
What is the difference between gTLDs and ccTLDs?
The Domain Name System (DNS) is a distributed directory based on a hierarchical name structure. The top of the hierarchy is the so-called “root” domain (administered by ICANN), from which branches are the so-called “top-level” domains. Examples of TLDs are .com, .org, .net, .pk, etc.
We distinguish between gTLDs (generic Top Level Domains: .com, .org, .net, .biz, .info …) and ccTLDs (country code Top Level Domains: the national suffixes of .pk, .ca, .uk, .us, .cn). TLDs start from new branches which are the so-called “lower level” domains (dmtwebhosting.com for example, looking for domain or PK domain registration in Pakistan then DMTwebhosting is the best choice).
Change of registrar
Once a domain name has been registered with a registrar (and the procedures carried out with the national body concerned in the case of a domain name whose suffix is a ccTLD), you may want to transfer the registration to the other registrar. During this procedure, the information relating to the domain name-IP address translation is kept during the transfer: any risk of service interruption is therefore avoided.
Change of host
More frequently, if we want to change the host, and we will no longer have to transfer the domain name registration but the destinations of requests to this domain name.
If you have a domain name, you are listed as the administrative contact for this domain name filed with the registrar. As such, it is possible for us to modify the authoritative “DNS” for this domain.
By “DNS” is meant here by abuse of language (Domain Name Server instead of Domain Name System) the information indicating the IP address and the hostname (which is nothing more than a domain name prefixed, e-g with ” www “) of the primary name server, and the information showing the IP address and hostname of the secondary name server. The difference between the two is as follows: the secondary server acts as a “spare tire” if, for example, the primary server fails.

The DNS converts domain names into IP addresses.
Definition of the word Domain Name
In the world of the Web, a domain name comes down to the identifier of an internet domain. The latter is itself defined as a group of computers that share a common characteristic and which are all connected to the Internet. The simplest example of a domain name is the .pk domain name used by most Pakistani sites to register pk domains in Pakistan. In fact, it is more precisely the Internet domain which groups together the computers which host activities registered with PKNIC (Pakistan Association for Internet Naming in Cooperation).
Today there are different types of domain names free, paid, first, second level, etc. A domain name is generally rented for a fixed period since it cannot be bought permanently. It has also been possible, in recent years, to obtain a personalized domain name based on a suffix for a large company, a large organization, etc.
