Data can be a network specification or a single IP. IP
addresses can be specified in all forms understood by
parseAddress(). The size of a network can be specified as
/prefixlen a.b.c.0/24 2001:658:22a:cafe::/64
-lastIP a.b.c.0-a.b.c.255 2001:658:22a:cafe::-2001:658:22a:cafe:ffff:ffff:ffff:ffff
/decimal netmask a.b.c.d/255.255.255.0 not supported for IPv6
If no size specification is given a size of 1 address (/32 for
IPv4 and /128 for IPv6) is assumed.
If make_net is True, an IP address will be transformed into the network
address by applying the specified netmask.
