Domain names are hostnames that provide more easily memorable names to stand in for numeric
IP
addresses. They allow for any service to move to a different location in the topology of the
Internet
(or another internet), which would then have a different IP address.
A domain name is required to give access to your website. It acts like a unique address that allows your site to be located throughout the Internet.
Domain names can have many different extensions. Each domain name extension is the responsibility of a certain registry. For example the .ie
ccTLD
(country-code Top Level Domain) is handled by the
Irish Domain Registry (
IEDR
).
Here are some more examples of domain name extensions:
example.com
example.net
example.org
example.biz
example.co.uk
