Filter fake IPs by type, according to resolved IPs' types
(e.g. if resolved IPs contain only IPv6 address, then return fake IPv4 address only. We don't want the client to choose fake IPv4 address, finding it embarrassing that we can't replace it with a resolved IPv6 address, because the RFC-3089-style proxify-ing hack requires the same matching type of fake IP and resolved IP)
