18.104.22.168 describe the purpose and organization of a domain name system (DNS)
It associates various information with domain names assigned to each of the participating entities.
It is most commonly used to obtain an IP address by hostname, obtain mail routing information and / or service nodes for protocols in a domain.
Domain name is part of the URL for a resource on the internet.
For example, nis.edu.kz, bzfar.org, vk.com
kz - top level domain name
edu - second level domain name
nis - third level domain name or subdomen
All websites have equivalent IP addresses.
Why a company use a domain name instead of an IP Address for their website?
