Reverse DNS broken for 2001:6f8/32 (Easynet)
[de] Christoph Schulz on Sunday, 29 January 2012 21:45:15
Hello, reverse DNS seems to be broken for 2001:6f8/32 address space due to the non-existing (?) nameserver ns2.easynet.net. I don't know for sure whether such a setup is allowed, but it definitely breaks the dig tool:
