[Samba] dynamic DNS updates by DHCP script only for IPv4
Hi folks, after having received great help from you guys, I dare to ask another question here. I am working with a system which has IPv6 enabled and where clients should update their AAAA records as soon as they have been assigned by the DHCPv6 server. (As a side-question: I know that DHCPv6 is not very common and that SLAAC is very common, but how do that people use DNSv6 registration then? Only DNS(v4) is only a workaround, given that the future may be IPv6 some time and as soon as dual-stack configurations are not necessary anymore, they have serious problems with name resolution of their clients which have their IP addresses automatically assigned. Or am I missing something?) I am using the script from the following page, which is working perfectly fine - for IPv4 addresses: https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records Is there a similar script (or an extension of the current one) also available for IPv6? (I don't think that I can update by myself...) Or (again) am I missing some important point and my issue can be solved differently? Best Tom

I do not have over sixteen million dhcp clients, so I do not use IPv6. If you wish to take and modify the existing script, then be my guest, just be aware, I will not be doing so. Rowland
