meaning of internet address

1. Internet address 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 hostss Internet address is sometimes related to its Ethernet address. The Internet address is usually expressed in dot notation, e. g. 128. 121. 4. 5. The address can be split into a network number or network address and a host number 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 Class C - high 3 bits 110, 21-bit network number, 8-bit host number. n1. n2. n3. a 192 <= n1 <= 223 The Internet address must be translated into an Ethernet address by either ARP or constant mapping. The term is sometimes used incorrectly to refer to a hosts fully qualified domain name. [Jargon File]
