www.xymon.com now available via IPv6 🔗 link

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

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

--- 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

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?

Hi Bruce,

Not at all, I'd rather know about these problems.

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.
