   <networking> (Internet address) The 32-bit number uniquely
   identifying a {node} on a network using {Internet Protocol},
   as defined in {STD} 5, {RFC} 791.  An IP address is normally
   displayed in {dotted decimal 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
   (but see also {CIDR}).  The class is 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

   {DNS} translates a node's {fully qualified domain name} to an
   Internet address which {ARP} (or {constant mapping})
   translates to an {Ethernet address}.
