IP Address
In the most widely installed level of the IP today, an IP address is a 32-bit binary digit
number that identifies each sender or receiver of information that is sent in packet form
across the Internet. When you request a Web page or send an e-mail, the IP part of
TCP/IP includes your IP address. IP sends your IP address to the IP address obtained by
looking up the domain name in the URL you requested or in the e-mail address to which
you are sending a note. A dynamic IP address is an IP address that is automatically
assigned to a client station in a TCP/IP network, typically by a DHCP server.
