 Posted: Mon Apr 04, 2022 5:29 am Post subject: install DNS update with ipv6 on a SLAAC config |
 |
|
I have a ipv6 subnet of my ISP which is advertised via the DSL modem,
I installed DHCPv6 server on a separate gentoo box to set domain name, DNS servers, and NTP.
I'd like it to register IPV6 addresses on my BIND DNS server as well, but no reason why it doesn't work.
DHCPDv6 logs (part of it):

The first line (which is exactly why I chose it) makes me think dhcpdv6 indeed tries to register. The fact it doesn't work for APBureau is irrelevant: it indeed has a static IP and as such a static record in DNS. But why doesn't it work ?
