Domain Name
Each server has its very own IP (Internet protocol) address, which
is a long string of numbers and dots. However, since we humans have
trouble remembering all those ooky numbers, the domain name was created.
The domain name in http://www.hotwired.com
is hotwired.com, and it acts as a substitute for the IP numbers. If
you really wanted to, you could type in a site's IP number, but it's
much easier to use the handy-dandy domain name and let the server
translate it using its DNS (domain-name-server) software.
Each top-level domain name has a suffix that indicates what kind of
organization is hosting the site:
com - commercial businesses
net - network organizations
edu - educational institutions
org - nonprofit organizations
gov - government agencies
mil - military
The first step toward getting yourself one of those yournamehere.com
addresses is to find a name that isn't taken. Once you find a free
name (there are plenty of companies out there that would love to
help you in your search), then you have to register it with Internic,
the organization that keeps track of which domain names correspond
with what IP numbers (there's a US$70 registration fee). And that's
not all. You have to keep on paying on an annual basis to keep that
domain name yours (a $35 maintenance fee). All in all, it can be
a fairly substantial investment in time and money. But if you plan
on having your own little corner on the Web for years to come, then
stake a claim now, because those names are going like hot cakes.
