>From Microsoft Computer Dictionary:

*IP* n. Acronym for Internet Protocol. The protocol within TCP/IP that
governs the breakup of data messages into packets, the routing of the
packets from sender to destination network and station, and the reassembly
of the packets into the original data messages at the destination. IP runs
at the internetwork layer in the TCP/IP model-equivalent to the network
layer in the ISO/OSI reference model. See also ISO/OSI reference model,
TCP/IP. Compare TCP.

*IP address* n. Short for Internet Protocol address. A 32-bit (4-byte)
binary number that uniquely identifies a host (computer) connected to the
Internet to other Internet hosts, for the purposes of communication through
the transfer of packets. An IP address is expressed in "dotted quad" format,
consisting of the decimal values of its 4 bytes, separated with periods; for
example, 127.0.0.1. The first 1, 2, or 3 bytes of the IP address identify
the network the host is connected to; the remaining bits identify the host
itself. The 32 bits of all 4 bytes together can signify almost 232, or
roughly 4 billion, hosts. (A few small ranges within that set of numbers are
not used.) Also called: Internet Protocol number, IP number. See also host,
IANA, ICANN, InterNIC, IP, IP address classes, packet (definition 2).
Compare domain name.

*IP address classes* n. Short for Internet Protocol address classes. The
classes into which IP addresses were divided to accommodate different
network sizes. Each class is associated with a range of possible IP
addresses and is limited to a specific number of networks per class and
hosts per network. See the table. See also Class A IP address, Class B IP
address, Class C IP address, IP address.
   Address Class Range of IP Addresses Networks per Class Hosts per Network
(maximum number)
      Class A (/8) 1.x.x.x to 126.x.x.x 126 16,777,214
      Class B (/16) 128.0.x.x to 191.255.x.x 16,384 65,534
      Class C (/24) 192.0.0.x to 223.255.255.x 2,097,152 254

IP address classes. Each x represents the host-number field assigned by the
network administrator.
