IP equals Internet ProtocolEvery computer connected to the Internet has a unique identifier called an IP address. On many networks the IP address of a computer is always the same, or "static". On other networks a random DHCP IP address is assigned and is referred to as a "dynamic" IP address. If a system uses dynamic addressing, the IP can change quite often. Read more... Protocol Directory Site contains information on all known networking protocols from ATM to IPX and TCP/IP. Well laid-out with HTML and PDF versions of protocol information.

CIDR Short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C, with CIDR. A single IP address can be used to designate many unique IP addresses. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP network prefix. Read more about CIDR at Webopedia.com or Wikipedia.com, "A CIDR-compliant address is written with a suffix indicating the number of bits in the prefix, such as 192.168.0.0/16. This permits more efficient use of increasingly scarce IPv4 addresses". Other terms in common use for CIDR are: Supernet and Subnet (Subnetting made classless Inter-Domain Routing possible). The difference between a classful and classless routing protocol is very simple. Classless protocols include the mask in the address while classful protocols do not.
