Intranet
A network based on TCP/IP protocols (an internet) belonging to an
organization, usually a corporation, accessible only by the organization's
members, employees, or others with authorization. An intranet's Web sites
look and act just like any other Web sites, but the firewall surrounding an
intranet fends off unauthorized access.
IP address
An identifier for a computer or device on a TCP/IP network. Networks using
the TCP/IP protocol route messages based on the IP address of the
destination. The format of an IP address is a 32-bit numeric address written
as four numbers separated by periods. Each number can be zero to 255,
for example 192.168.0.1.
Public IP addresses are LAN IP addresses that can be considered "legal"
for the Internet because they can be recognized and accessed by any
device on the other side of a connection. In most cases your ISP allocates
them.
Private IP addresses are also LAN IP addresses, but are considered
"illegal" IP addresses to the Internet. They are private to an enterprise while
still permitting full network layer connectivity between all hosts inside an
enterprise as well as all public hosts of different enterprises.
