Handle: JJ43-SIXXS Tunnel: T25469 2001:1af8:fe00:20d::2 Subnet: R26245 2001:1af8:fec8::/48 Problem description: Reverse DNS of my subnet does not work reliably, sometimes a remote host (e.g. an IRC server) can resolve my IPv6-addresses and sometimes not. It seems ns2.sixxs.net does not delegate to my nameservers whereas ns1.sixxs.net and ns3.sixxs.net do. Reverse delegation was requested about 20 hours ago, ns1 and ns3 picked it up rather quickly, but ns2 hasn't yet. SOA-serials of "e.f.8.f.a.1.1.0.0.2.ip6.arpa." suggest ns2 is a few weeks behind ns1 and ns3. Requested action: Inform me whether I am being impatient or whether there is some issue with ns2.sixxs.net. If the latter, please make ns2 also delegate "8.c.e.f.8.f.a.1.1.0.0.2.ip6.arpa." to "nvidium.soleus.nu." and "ns2.afraid.org." Dig output: http://pastie.org/private/5nor5ironwjztzgenm8wgg Information about OS, firewall, routing, etc. omitted since there is no connectivity problem, just reverse DNS.
