Dear all, I have tried to configure a zone containing a range of IPV6 PTR records. My target was to see how it is possible to configure such a zone to always return the same answer for all the IPV6 IP’s in the range. And if possible to return specifi names for specific IP’s. Example of a IPV6 range: 1234:5678:90ab:00cd::/56 Creation of the zone è “0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa.” In the zone, I have put the following PTR record: *.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR 123.lebrol.be. It seems (according to some of my tests) that for all IP’s in the range, the reverse is “123.lebrol.be.” Question è is this a correct way to configure reverse IPV6 if we accept the same name for all the IP’s in the range? Zone modification: I have tried to add in the zone file the possibility to answer a specific name to a specific IP in the range and keep answering the general name to all the other IP’s in the range. *.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR 123.lebrol.be. 1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.1.2.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR nombre.de.cerise.be. è specific IP It works when the specific IP is used: lennydnstest01:~# dig @localhost -x 1234:5678:90ab:0021:0fed:cba9:8765:4321 ;; QUESTION SECTION: ;1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.1.2.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. IN PTR ;; ANSWER SECTION: 1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.1.2.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR nombre.de.cerise.be. But if another IP in the range is used having the following nibbles mapping the specific PTR (here 1.2 ), it do not work and nothing is found! lennydnstest01:~# dig @localhost -x 1234:5678:90ab:0021:: ;; QUESTION SECTION: ;0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.2.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. IN PTR ;; AUTHORITY SECTION: 0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN SOA ns1.uat.skynet.be. dnsmaster.skynet.be. 5 10800 3600 3600000 3600 Can someone give an explanation on the use of the wildcard *.Any other way to obtain the desired result? Thanks in advance for your feedback, Hugo,
