IPv6 support?

[webernetz]

Hi Sebastian,

thanks for your great tool. One issue: It looks like it uses IPv4 only. Some of my own name servers (which I tested with your tool) also provide IPv6. Hence it would be great if your checks (ping, nmap, zone transfer, ...) would also run against the IPv6 addresses and not only to the v4 ones.

Cheers,
Johannes

This is very good request. And maybe not difficult. I will put it in the TODO. Of course if you want to give it a go, just tell me.
