List addresses for the specified host (do a name lookup).

Returns a list of host addresses to that can used with bind() or connect().

Can specify a filter for a specific capability (tcp or udp).

This will carry out a name resolution and return the list of addresses that map to the host name.

If both ipv4 and ipv6 are specified, ipv6 addresses are preferred.

Lists all associated addresses.
