Lists shared IP addresses for virtual servers

This command outputs a list of shared IP addresses that can be used by new
or existing virtual servers.

Output is in table format by default, but you can switch to a more detailed
and easily parsed list with the C<--multiline> flag. Or to just get a list
of addresses, use the C<--name-only> parameter.

By default only shared IPv4 addresses are shown, but you can use the C<--ipv6>
flag to also include IPv6 addresses.
