As an example, in the domain example.co.uk, co is the second-level domain. Many desirable domain names are already assigned and users must search for other acceptable names, using Web-based search features, or WHOIS and dig operating system tools.

Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. A domain name server (also called DNS) is the Internet’s equivalent to a phone book. An IP address (Internet Protocol address) is a unique identifying string of numbers (like 75.98.175.110) which are given to every individual computer, server and network on the Internet.
