Meaning of INTERNET ADDRESS

 
Computing Dictionary
 
 Definition: 
  1. (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. 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 host's fully qualified domain name.

  2. (Note lower case "i"). An ip address that uniquely identifies a node on an internet.
