Internet Control Message Protocol is an Internet protocol

IP Address

A 32-bit address assigned to hosts using TCP/IP. It belongs to

separated by periods formatted as dotted decimals.

Each address has a network number, an optional sub network

number and a host number. The first two numbers are used

host within the network or sub network. A subnet mask is
used to extract network and sub network information from
the IP address.

optical fibre to carry voice, digital network services and
video. ISDN is intended to eventually replace the plain old
telephone system.

Kerberos was created by MIT as a solution to network

(and vice versa) across an insecure network connection.
