DHCPv6 domain-search list not sent to clients

Description

After tcpdumping dhcp requests and responses I realized that `option domain-search` in `/var/dhcpd/etc/dhcpdv6.conf` should be `option dhcp6.domain-search`. I have verified this by patching the file manually and restarting the process (manually). After this the DHCP server properly sends the search list when requested by the client.

#6 Updated by Magnus Holmgren 5 months ago

Same thing with option domain-name, I'm pretty sure. Has that been fixed too?

#7 Updated by Magnus Holmgren 5 months ago

No, wait, such an option doesn't even exist. So should the text box be removed completely from the UI?

Correct option is present now.
