A (address) resource record

A records list the address for a given machine. The ``name'' field is the machine name and the address is the network address. There should be one A record for each address of the machine. Here is an example of an address record for a machine named volga with two network addresses:

   {name}    {ttl}   addr-class   A   address
   volga             IN           A   10.0.118.1
                     IN           A   10.0.246.1
