For example, when a Web address (URL) is typed into a browser, a DNS query is made to learn an IP address of a Web server associated with that name. Using the www.example.com URL, example.com is the domain name, and www is the hostname. DNS resolution maps www.example.com into an IP address (such as 192.0. 2.1).
What is a hostname in DNS?
A DNS hostname is a name that uniquely and absolutely names a computer; it’s composed of a host name and a domain name. DNS servers resolve DNS hostnames to their corresponding IP addresses.
What is a host name example?
A host, or website, on the Internet is identified by a host name, such as www.example.com . Host names are sometimes called domain names. Host names are mapped to IP addresses, but a host name and an IP address do not have a one-to-one relationship.
Is DNS name and hostname same?
Internet hostnames may have appended the name of a Domain Name System (DNS) domain, separated from the host-specific label by a period (“dot”). In the latter form, a hostname is also called a domain name.
