All you ever wanted to know about
OK... The answer is
"business.com" sold for $7.5
million in late 1999. In May of 1985 there was only one .com
domain registered (think.com). In October, the second .com
domain was registered. By October of 1991, there were 165 .com,
22 .org, 20 .net, 285 .edu and 3 .us domains registered. Two
years later, there were approximately 600 .coms registered. By
1995, the number of registered domains was at 6000, and two
years later the number topped 22,000. Now, there have been over 15 million domain
names registered to date, including well over 9 million names
ending in .com...
Now that that's out of the way let's get down
So what is a domain name? Let's
equate a domain name with a persons name in a phone book. If you
want to call someone you look their phone number up in a phone
book. Just imagine what it would be like if there were just
numbers... Unless you knew the person and they gave you their
phone number it would be impossible to find their number.
This leads us to DNS (Domain Name
System). What is DNS? DNS is A database system that translates a
domain name into an IP address. For example, a domain name like
goaskal.net translates into an IP address of 18.104.22.168.
Every time you use a domain name, a DNS service must translate
the name into the corresponding IP address. IP stands for
internet protocol (the protocol used to route a data packet from
its source to its destination over the internet). The DNS system
is, in fact, its own network. If one DNS server doesn't know how
to translate a particular domain name, it asks another one, and
so on, until the correct IP address is returned. Going back to
the phone number example above, DNS acts like an electronic
phone book which not only finds the number but dials it also.
Whew... So far so good... Now your
asking how the DNS is handled. It is handled through nameservers
designated as NS. Nameservers are computers that translate a
numeric address assigned to every computer connected to the
internet (IP Address= internet protocol address->the protocol
used to route a data packet from its source to its destination
over the internet) into the domain names we are all familiar
with. These are broken down into primary nameservers and
secondary nameservers. The Primary nameserver contains
authoritative information for the domain name and is used to
resolve that domain name to its corresponding IP number(s). The
designation of "primary" means that this name server will be
used first and will be relied upon before any of the other name
servers. Secondary nameservers are used in addition to and
as a backup for the primary name server.
Nameservers come into play after you
have your domain name and you get ready to host a web site using
your new domain name. Who ever you decide to use as you7 HSP
(hosting service provider) will tell you what nameservers you
should point to. They will look something like NS.apbsc.com and
NS2.apbsc.com. The one with the NS designation will be the
primary nameserver. All the others will be secondary nameservers.
Do I need a domain name? Well why not? They are relatively
inexpensive, $10-$35 per year. It will give you the ability to
have an Email address @your-domain.com/net instead of @lycose or
@yahoo or @aol. If you own a business you absolutely need one!
There isn't a less expensive way to advertise anywhere. Want to
start a business? Whay not start an internet business with your
own domain name?
How do I pick a domain name? What's
the best name for me? Should I get a .com. .net, .biz, etc.? For
