Given a resolv.conf that looks like nameserver 2001:db8:6:5:4:3:2:1 options edns0 running local-unbound-setup produces a file /etc/unbound/forward.conf that looks like this: # This file was generated by local-unbound-setup. # Modifications will be overwritten. forward-zone: name: . Notably missing is a line on the end that should look like forward-addr: 2001:0db8:6:5:4:3:2:1 If the ipv6-adress contains the sequence "::" the script works as expected.
This worked in FreeBSD 11.3, so we have a regression here.
