Multiple IPs Associated With A Single Name

[John Miller]

Hi Tim,

AFAIK, multiple A records are the only way to return multiple IPs for
a given FQDN.  there are multiple A records for a given name, BIND
will return all of those records -- it'll return all the IPs.  It's up
to the client in question to decide how to use that information.
