I've found that adding the following to dhclient.conf seems to resolve this. Not sure if there is a way to get this working out of the box.
/etc/dhcp/dhclient.conf #send host-name = gethostname(); send host-name = "<serverhostname>"; # for ipv6 /dhcpdv6 send fqdn.fqdn "<serverhostname.domain.com>."; send fqdn.encoded on; send fqdn.server-update on; obviously I replace <serverhostname*> with the correct hostname. With these settings in place the dhcpd6 server receives the correct info to perform a ddns update. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1604617 Title: dhclient does not send fqdn.fqdn for DHCPv6 Status in isc-dhcp package in Ubuntu: New Bug description: ISC DHCP's dynamic DNS updates rely on the fqdn.fqdn option being sent in order to work for DHCPv6. This used to be done in Ubuntu, as shown in bugs #991360 and #108862, and all my Windows hosts send it. However this was removed in Ubuntu due to a regression in IPv4 functionality. As IPv6 is more widely deployed these days, this regression in IPv6 should be fixed. This bug is current as of Ubuntu 16.04 LTS.
