In computer networking, a domain typically refers to a domain name.
This would be the human-readable identifier for an Internet Protocol (IP) resource.
All devices on the internet are addressed via IP addresses.
While these are great for computers to use, theyre not particularly memorable for people.
Note:Facebook has a vanity IPv6 address with the string face:b00c in it.
To make it easier to browse the internet, the Domain Name System or DNS was created.
DNS offers human-readable domain names that DNS servers can translate into IP addresses.

The Structure of a Domain Name Start at the End
Domain names have a standard structure.
This domain name has three parts.
From right to left, you have the TLD, then the domain name, and finally the subdomain.
TLD stands for top-level domain.
There are technically two variants, denoted by ccTLD and gTLD.
The cc stands for country code while g stands for generic.
For example, the ccTLD .ua is the code for Ukraine.
Some countries have chosen to restrict the use of their ccTLDs to people or companies from the country.
In contrast, others allow anyone to register domains using their ccTLD.
For example, Columbia (.co) allows anyone to use their ccTLD.
Generic TLDs are not related to any country.
The most well-known example would be .com but there are many others including .edu .mil .gov .org and .net.
Some of these also have restrictions on who can register a domain under the gTLD.
For example .mil is exclusively for military sites and .gov is exclusively for government sites.
The Actual Domain in a Domain Name
The actual domain name forwww.technipages.comis technipages.
The www part on the front is known as a subdomain.
Domain names must be unique within a top-level domain.
Domain names are case insensitive.
This means thatwww.technipages.comandwww.Technipages.comwill resolve to the same IP address.
A subdomain is simply a prefix on the front of a domain name.
These also have to be registered and advertised separately on a DNS server.
Still, you dont need to purchase the rights to a subdomain.
Owning a domain, confers the rights to any subdomain.
Its possible to nest subdomains an arbitrary number of times, though some software may have limits.
For example, you could have bank.of.america.com.
