PTR does not work

Hello, today I noticed, that no tunnel IP has a working PTR record. A few days ago the resolving of IPv6 adresses into hostnames must have worked, because I'm running a mailserver on one IP of the tunnel subnet and the only mailserver I currently reach via IPv6 is bouncing messages when no PTR is present. First, I checked both of my authorative DNS servers, but they're working properly. Heres the result of a "dig" on one tunnel IP, but it's represantative for other IPs: <code> rejectix:~# dig -x 2a01:198:490::e +trace ; <<>> DiG 9.5.1-P3 <<>> -x 2a01:198:490::e +trace ;; global options: printcmd . 84163 IN NS j.root-servers.net. . 84163 IN NS f.root-servers.net. . 84163 IN NS b.root-servers.net. . 84163 IN NS k.root-servers.net. . 84163 IN NS a.root-servers.net. . 84163 IN NS e.root-servers.net. . 84163 IN NS c.root-servers.net. . 84163 IN NS m.root-servers.net. . 84163 IN NS l.root-servers.net. . 84163 IN NS g.root-servers.net. . 84163 IN NS d.root-servers.net. . 84163 IN NS i.root-servers.net. . 84163 IN NS h.root-servers.net. ;; Received 509 bytes from 78.46.93.84#53(78.46.93.84) in 35 ms ip6.arpa. 172800 IN NS ns.icann.org. ip6.arpa. 172800 IN NS ns2.lacnic.net. ip6.arpa. 172800 IN NS sec1.apnic.net. ip6.arpa. 172800 IN NS ns-sec.ripe.net. ip6.arpa. 172800 IN NS tinnie.arin.net. ;; Received 229 bytes from 2001:500:3::42#53(l.root-servers.net) in 162 ms 0.a.2.ip6.arpa. 84600 IN NS ns2.lacnic.net. 0.a.2.ip6.arpa. 84600 IN NS ns-pri.ripe.net. 0.a.2.ip6.arpa. 84600 IN NS tinnie.arin.net. 0.a.2.ip6.arpa. 84600 IN NS sec3.apnic.net. 0.a.2.ip6.arpa. 84600 IN NS sec1.apnic.net. ;; Received 302 bytes from 2001:610:240:0:53::4#53(ns-sec.ripe.net) in 45 ms 8.9.1.0.1.0.a.2.ip6.arpa. 172800 IN NS ns1.dnspartner.de. 8.9.1.0.1.0.a.2.ip6.arpa. 172800 IN NS ns2.dnspartner.de. ;; Received 139 bytes from 2001:dc0:2001:a:4608::59#53(sec1.apnic.net) in 395 ms 8.9.1.0.1.0.a.2.ip6.arpa. 86400 IN SOA ns1.dnspartner.de. hostmaster.speedpartner.de. 2010051100 28800 7200 604800 86400 ;; Received 167 bytes from 84.19.176.110#53(ns2.dnspartner.de) in 38 ms </code> Could you check, if your PTRs are working? Or does it have something to do with the "DENIC desaster" today? Thank you for your work! Much greetings from Wuppertal, Germany

Today it works pretty as ever :-) Maybe it had something to do with the deleted .de zone...
