Put two reverse records in both the IPv4 and IPv6 reverse zones.... in the "125.124.123.in-addr.arpa" zone:
126 IN PTR mail.xxx.com. 126 IN PTR ns.xxx.com. and the same sort of thing in the reverse IPv6 zone. To calculate run:- 2a01:e34:xxxx:xxxx:xxxx:xxxx:1122:3344 and see what question dig asks. Nothing wrong with a machine (or interface on a machine) having more than one name for the same address. List them all in the reverse configuration. After all, a NS record usually has at least two records ;-) On 18/06/2017 15:40, Pierre Couderc wrote: > Well, we have 2 computers in xxx.com subnet provided by ISP on > 123.124.125.126 ipV4 address and corresponding IPV6 segment > > mail.xxx.com : 2a01:e34:xxxx:xxxx:xxxx:xxxx:1122:3344 for mail server > ns.xxx.com : 2a01:e34:xxxx:xxxx:xxxx:xxxx:aabb:ccdd for dns server > > In xxx.com bind : > > mail A 123.124.125.126 > mail AAAA 2a01:e34:xxxx:xxxx:xxxx:xxxx:1122:3344 > > ns A 123.124.125.126 > ns AAAA 2a01:e34:xxxx:xxxx:xxxx:xxxx:aabb:ccdd > > What should I put for IPV4 reverse address : if I put mail.xxx.com, > the reverse address will not point on ns.xxx.com, and if put > ns.xxx.com, the reverse dns will not point on mail.xxx.com, and I > shall have mail problem. > > What are the best practices fore thus problem ? > > Thanks > PC > > > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to > unsubscribe from this list > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users -- Mark James ELKINS - Posix Systems - (South) Africa m...@posix.co.za Tel: +27.128070590 Cell: +27.826010496 For fast, reliable, low cost Internet in ZA: https://ftth.posix.co.za _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
