IPv6 connectivity

Posted by dale on Fri, 31 Dec 2004 11:16:54 EST

When I installed FreeBSD onto my server it setup an IPv6 address, funky I thought although I’m never going to use it. Anyway my Mac is also built on BSD and it too has an IPv6 address. So I tried a normal ping but it only supports IPv4 so I tried typing ping6 and it worked! Cool!

So anyway I now have two computers talking to each other with IPv6.

electra:~ michaeldale$ ping6 -I en1 fe80::200:e8ff:fe6c:557b

Also that connection is running over my wireless, pretty fast I thought. :)

Below are the comments for this news item

Crap. IPv6 scares me. Are there reserved private use IP ranges (Class A/B/C - 10.x.x.x/172.16-31.x.x/192.168.x.x - equivalents?) or what? That makes remembering MAC addresses look easy…

I use G protocal as well for my wireless. =)

Yep I'm pretty sure there are.

I don't think 802.11b or 802.11g would make all that much difference with pings. I was just impressed with 1-2ms because it is going through the air, plus it is doing encryption on the fly.
