[ Bcc: David and Noah ] Hi,
I’m the maintainer for Kea and ISC-DHCP on OpenWRT. The scripting to take the UCI configuration files for DHCP and mangle them into Bind zone transfers is here: https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L136-L186 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L274 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L276 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L569 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L575 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L581-L606 https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L694 and the glue in Bind is here: https://github.com/openwrt/packages/blob/master/net/bind/files/bind/named.conf#L8-L9 An example is running locally here, where I have “redfish-solutions.com <http://redfish-solutions.com/>” and “168.192.in-addr.arpa” as the domains I serve. ; Generated by /etc/init.d/dhcpd at Mon Dec 1 13:14:10 MST 2025 ttl 3600 update add Bedroom.redfish-solutions.com.

Lastly, if I query a local host A record that works. But when I query that address for a PTR record it fails. root@OpenWrt:~# dig -t a macmini2.redfish-solutions.com. ; <<>> DiG 9.20.15 <<>> -t a macmini2.redfish-solutions.com. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 23297 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1232 ; COOKIE: 39141732f1eb310601000000692dfcb178eb0b0ac919a619 (good) ;; QUESTION SECTION: ;macmini2.redfish-solutions.com.

The top of my dhcpd.conf file looks like: authoritative; ddns-domainname "redfish-solutions.com."; ddns-update-style standard; ddns-updates on; ignore client-updates; update-static-leases on; use-host-decl-names on; update-conflict-detection off; update-optimization off; include "/var/run/named/session.key"; zone redfish-solutions.com. { primary 127.0.0.1; key local-ddns; } zone 168.192.in-addr.arpa. { primary 127.0.0.1; key local-ddns; } My named.conf file contains: options { … // This is used e.g. by isc-dhcp allow-new-zones yes; … }; It’s probably something simple but at this point I can’t see the forest for the trees…. Please help me get a patch out the door quickly. Thanks -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list.
