Hi,
if any of you are connected via IPv6, then www.xymon.com and the mailing list server is now available directly through IPv6, at this easy-to-remember address: 2001:16d8:dda8:0:21c:c0ff:fec0:1875
You don't have to worry about that since DNS has also been updated, so it should all happen automatically.
This also means I now have the ability to actually test some IPv6 code, so there is a much better chance of Xymon getting IPv6 support now.
Regards, Henrik
Not to be a wet blanket, but DNS is mildly hosed.
ping xymon.com PING xymon.com (90.184.111.80) 56(84) bytes of data.
ping www.xymon.com ping: unknown host www.xymon.com
A lot of "stuff" in google points to www.xymon.com

Looks fine from here: Daniel-McDonalds-iMac:~ $ host www.xymon.com www.xymon.com has address 90.184.111.80 www.xymon.com has IPv6 address 2001:16d8:dda8::21c:c0ff:fec0:1875 Daniel-McDonalds-iMac:~ $ host xymon.com xymon.com has address 90.184.111.80 xymon.com mail is handled by 10 mx.xymon.com.

That's a strange response.
1$ host www.xymon.com www.xymon.com has address 90.184.111.80 www.xymon.com has IPv6 address 2001:16d8:dda8:0:21c:c0ff:fec0:1875
2$ ping www.xymon.com PING www.xymon.com (90.184.111.80): 56 data bytes ^C --- www.xymon.com ping statistics --- 105 packets transmitted, 0 packets received, 100.0% packet loss
3$ ping 90.184.111.80 PING 90.184.111.80 (90.184.111.80): 56 data bytes ^C --- 90.184.111.80 ping statistics --- 23 packets transmitted, 0 packets received, 100.0% packet loss
Clearly, with the header showing the proper IP address, dns is working.
However, www.xymon.com doesn't respond to ping. That's probably by design.
What OS are you using that gives a bad response in ping?

that's my firewall dropping your ping. DNS is ok here...
ping www.xymon.com ping: unknown host www.xymon.com
but not here.
I think I've got it fixed now, but it may take 12 hours for the change to propagate out (DNS caching and all).
It's weird. I had
- an A record for xymon.com = 90.184.111.80
- an AAAA record for xymon.com = 2001:16d8:dda8:0:21c:c0ff:fec0:1875
- a CNAME for *.xymon.com = xymon.com and that apparently breaks.
Even weirder, if I do a "dig www.xymon.com" I get an error (so that matches your experience). But if I do a "dig +trace www.xymon.com" it finds the IPv4 address just fine.
I think the wildcard CNAME is the culprit, but I am not quite sure why.
