Re: Mass ipv6 lookups
So in other words I'm SOL. I guess I don't agree that a system should do
2 lookups (ipv4 ipv6) every time. It should be a configuration option
really. You should be able to say one or the other. It truly is a waste
of time.
Just so you know, I have found that anything TCP wrapped (ssh, ftp...),
smtp, http, all now complete ipv6 lookups. This in some ways is I dare
say a Microsoft tactic. Shove it down my throat until I concede.
