Description of problem: Enabling DHCPDv6 on the network causes the problem that when running both dhcpv4 and v6 services on the same server, dhcp service does not allow for an exsisting v4 record to be updated with v6: Aug 23 13:41:14 ls2ka dhcpd: DHCPDISCOVER from f4:ce:46:3d:55:62 via eth0 Aug 23 13:41:15 ls2ka dhcpd: DHCPOFFER on 192.168.168.13 to f4:ce:46:3d:55:62 (NPI3D5562) via eth0 Aug 23 13:41:19 ls2ka named[13070]: client 192.168.168.3#35690: updating zone 'elton-intra.net/IN': adding an RR at 'NPI3D5562.elton-intra.net' A Aug 23 13:41:19 ls2ka named[13070]: client 192.168.168.3#35690: updating zone 'elton-intra.net/IN': adding an RR at 'NPI3D5562.elton-intra.net' TXT Aug 23 13:41:20 ls2ka named[13070]: zone elton-intra.net/IN: sending notifies (serial 65586) Aug 23 13:41:20 ls2ka dhcpd: Added new forward map from NPI3D5562.elton-intra.net to 192.168.168.13 Aug 23 13:41:20 ls2ka named[13070]: client 192.168.168.3#35310: updating zone '168.168.192.in-addr.arpa/IN': deleting rrset at '13.168.168.192.in-addr.arpa' PTR Aug 23 13:41:20 ls2ka named[13070]: client 192.168.168.3#35310: updating zone '168.168.192.in-addr.arpa/IN': adding an RR at '13.168.168.192.in-addr.arpa' PTR Aug 23 13:41:20 ls2ka named[13070]: zone 168.168.192.in-addr.arpa/IN: sending notifies (serial 1997111065) Aug 23 13:41:20 ls2ka dhcpd: added reverse map from 13.168.168.192.in-addr.arpa. to NPI3D5562.elton-intra.net Aug 23 13:41:20 ls2ka dhcpd: DHCPREQUEST for 192.168.168.13 (192.168.168.3) from f4:ce:46:3d:55:62 (NPI3D5562) via eth0 Aug 23 13:41:20 ls2ka dhcpd: DHCPACK on 192.168.168.13 to f4:ce:46:3d:55:62 (NPI3D5562) via eth0 Aug 23 13:41:58 ls2ka dhcpd: Solicit message from fe80::f6ce:46ff:fe3d:5562 port 546, transaction ID 0xA37D0000 Aug 23 13:41:58 ls2ka dhcpd: Sending Advertise to fe80::f6ce:46ff:fe3d:5562 port 546 Aug 23 13:41:58 ls2ka dhcpd: Request message from fe80::f6ce:46ff:fe3d:5562 port 546, transaction ID 0x735C0000 Aug 23 13:41:58 ls2ka dhcpd: data: leased_lease: not available Aug 23 13:41:58 ls2ka named[13070]: client 192.168.168.3#32899: updating zone 'elton-intra.net/IN': update unsuccessful: NPI3D5562.elton-intra.net: 'name not in use' prerequisite not satisfied (YXDOMAIN) Aug 23 13:41:58 ls2ka named[13070]: client 192.168.168.3#43688: updating zone 'elton-intra.net/IN': update unsuccessful: NPI3D5562.elton-intra.net/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) Aug 23 13:41:58 ls2ka dhcpd: Forward map from NPI3D5562.elton-intra.net to fdf5:a3af:1d9a::1f4 FAILED: Has an address record but no DHCID, not mine.

Install dhpd v4 and v6 2. Configure them to reply to queries and update the dns (DDNS) 3. Actual results: Can't update both v4 and v6 on the same server Expected results: Succesful updates to be preformed for both ipv4 and ipv6 address records. Additional info:
I assume this is being caused by the fact that i am not using the "ignore-client-updates;" option in dhcpd.conf? And that that is why a "TXT" record is being added for every dhcpv4 client that is not updating the dns records itself? And if I am supposed to add the "ignore-client-updates;" option to the dhcpd.conf, will I have to manually remove the "TXT" records for those clients from the zone file? And also remove those client's entries from the dhcpd.leases file as well? Please help me. regards, Eddie.
Hello Eddie, I'm afraid I don't have any answer for you at the moment, cause I don't have any spare time to investigate this right now. The best you can do is to try the dhcp-users mailing list. https://lists.isc.org/mailman/listinfo/dhcp-users
