Hi, in case of classless IN-ADDR.ARPA delegations(http://www.ietf.org/rfc/rfc2317.txt) I have usually seen at least one NS record pointing to name server other than the end-customer ones. Example from rfc2317.txt where there are two NS records and the second one is not the end-customer name server:
; <<0-127>> /25 0/25 NS ns.A.domain. 0/25 NS some.other.name.server. ; 1 CNAME 1.0/25.2.0.192.in-addr.arpa. 2 CNAME 2.0/25.2.0.192.in-addr.arpa. 3 CNAME 3.0/25.2.0.192.in-addr.arpa. ; Another example from one real name server zone file: ; 0 IN NS ns.content-providerA.com. 0 IN NS ns2.content-providerA.com. 0 IN NS ns.isp-of-content-providerA.net. ; 1 IN CNAME 1.0.47.168.192.in-addr.arpa. 2 IN CNAME 2.0.47.168.192.in-addr.arpa. 3 IN CNAME 3.0.47.168.192.in-addr.arpa. ; Is NS record pointing to "some other name server" needed in case of classless IN-ADDR.ARPA delegations? What happens if one does not specify this? regards, Martin _______________________________________________ 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
