Reverse DNS not working for 2a01:1e8:e107::/48
![[de]](/s/countries/de.gif) Shadow Hawkins on Monday, 30 January 2012 07:31:15
Reverse DNS is not working for the subnet. Configuration is done and local I can lookup it but a trace didn't find the nameserver...

Hi
i added a dns-server for the subnet in $SUBJECT. Resolving ip-addresses locally works. But externally i got only this:
dig +trace 2a01:1e8:e100:80df::1

That command indeed won't work, you need a -x to it to search the ip6.arpa tree, but then indeed it ends at Interscholz. I've forwarded the issue to them for resolution.

Reverse DNS not working for 2a01:1e8:e107::/48
The delegation from RIPE is now towards Interscholz and then for the /40 towards ns{123}.sixxs.net, thus all should be fine for this now.
