How to specify IPv6 IP address in forwarders{} section in /etc/named.conf.

Issue

• How to specify IPv6 IP address in forwarders{} section in /etc/named.conf.

Ex)This is the DNS server's IPv6 IP address used for forwarders in this case as follows.

# ip -o a
2: ens3    inet6 fe80::3faf:2ab1:b0bf:b071/64 scope link tentative noprefixroute dadfailed \       valid_lft forever preferred_lft forever

This is a short-styled that IPv6 IP address specified in forwarders{} section in zone entry.

#  cat /etc/named.conf

zone "redhat.com" IN {
  type forward;
  forward only;
  forwarders { fe80::3;
  };
};

With this forwarders setting, dig command fails with SEVERFAIL as follows.

# dig @fe80::3 test.redhat.com AAAA
