networking (IP address, TCP/IP address) The 32-bit host
address defined by the Internet Protocol in STD 5, RFC
791. It is usually represented in dotted decimal notation.
A hosts's Internet address is sometimes related to its
Ethernet address. The Internet address is usually expressed
in dot notation, e.g. The address can be split
into a network number (or network address) and a hostnumber unique to each host on the network and sometimes also
a subnet address. The way the address is split depends on
its "class", A, B or C as determined by the high address bits:
Class A - high bit 0, 7-bit network number, 24-bit host
number. n1.a.a.a 0 #@= n1 #@= 127
Class B - high 2 bits 10, 14-bit network number, 16-bit host
number. n1.n2.a.a 128 #@= n1 #@= 191
