Hi All,
On an older Bind server such as 9.3.6-p1, I can run dig +trace <A HREF="http://www.pccc.com">www.pccc.com</A>.
However, when I'm using 9.8.1-p1 and seeing a problem that stops the
trace when it reaches our IPv6 nameserver, ns3.pccc.com. Examples follow.
Am I doing something wrong with the newer dig?
Regards,
KAM

Likely because ns3 has only ipv6 address and no ipv4 address and the server you are checking from has no ipv6 capability.<BR>
You are asking for big problems using this method.<BR>
You should give all NS records an IPv4 address, and then add in IPv6 on the ones you can<BR>
<BR>
eg:<BR>
<BR>
ns2 A ip.v.4.add<BR>
ns2 AAAA ip:6:addr<BR>
<BR>
I guess the old versions are not so strict on checking, or dont know what to do about ipv6<BR>
