Internet Address questions:
There are two types of Internet addresses--domain addresses made up of
words separated by dots (for example, world.std.com), and IP addresses
made up of four numbers separated by dots (for example, 220.127.116.11).
Both types represent computer addresses on the Internet, and for many
purposes, either type can be used. Numbered IP addresses represent
specific computers on the Internet. Domain addresses may represent a
specific computer or may be less specific.
Domain name addresses all end with a correct top-level domain. The top-level domains may be any of these:
- a two-letter country code, such as us, uk, or mx. See the country code table.
A complete domain address adds one or more terms to the left of the
top-level domain, separated by dots. The top-level domain at the right is the most general; each term to the left is more specific.
The Internet Corporation for Assigned Names and Numbers (ICANN) announced a new series of top level domains to become available for registration in 2001. They are:
IP, or Internet Protocol, addresses consist of four numbers from 0 to
255, separated by dots. The first number is the most general, and each
following number is more specific.
A network might be assigned the hypothetical numbers 18.104.22.168 through
22.214.171.124. This would give them 256 numbers to use. A very large
network might be given all numbers beginning with, for example, 125.211.
This would give that network approximately 65 thousand addresses to use
from 126.96.36.199 through 188.8.131.52. More commonly, a network will
be assigned a portion of the range appropriate to its size.
