When might a DNS server provide multiple answers to a single name lookup, and why?
What will be an ideal response?
A DNS server provides several answers to a single name lookup whenever it possesses them, assuming that
the client has requested multiple answers. For example, the server might know the addresses of several mail
servers or DNS servers for a given domain. Handing back all these addresses increase the availability of the
mail service and DNS respectively.
