If it weren't for the domain name system (DNS), it would be difficult to
do the things we expect our computer to do these days, like contact each
other, display email, or open web pages. We take it for granted,
because it seems so easy — but every time we type in a web site address,
the Internet Protocol (IP) uses the address as well as the DNS to deliver
information from computer to computer.
What, exactly, is a domain name?
Domain names are the text names that correspond to numeric IP addresses
of computers connected to the Internet. Each domain name is unique,
and Internet users generally access websites by their domain names.
Mnemonic domain names can provide important clues to the content or
branding of a website. For this reason, memorable domain names, or
names associated with popular search terms like business,
investing, shopping, or travel, often command
high market values. Domain names ending with the popular .com
TLD (top-level domain) extension are the most sought-after, followed by
those with other generic TLDs such as .net and .org, and
those with country code or regional TLDs like .us, .ca, and
.eu. Because the Internet is growing by leaps and bounds, the
domain name system is constantly expanding and new domains are being
registered and sold frequently.
How do DNS servers work? In a nutshell, the web browser matches the
requested URL's domain name to an IP address. The web browser goes
first to a local server maintained by your Internet Services Provider
(ISP), and if the IP address is also local, the connection is made.
If the connection is not local, the local server contacts the root domain
server, which tells the local server where to find the information.
The local name server contacts the primary name server for the information
and sends it on to you!
As with any investment commodity, whether it be real estate, rare coins,
or corporate stocks, there is a market for domain names. This market
is supported by a number of domain name brokers, who focus on appraising,
buying, and selling domain names for corporate buyers, web developers,
and domain name investors. Some domain names, such as Business.com,
Diamond.com, and Loans.com, have sold for millions of dollars, and the
interest in short, high-quality names remains high. On this site,
domain-name-system.us, you will find domain name brokers, registrars,
and information concerning this sometimes speculative investment vehicle.
