Comment (by arma):

 Replying to [comment:9 teor]:
 > 1. If it is a valid IPv4 or IPv6 address, it is not a hostname

 I don't understand why we're making this complicated.

 This string_is_valid_hostname() thing is only used in our socks handshake,
 right?

 If we define hostname to be "anything that is a valid destination", then
 everything becomes simple, right?
