describing a conversion.
To convert the IPv6 address as the hostname, so do not properly forward.
This patch has not fully tested.
>How-To-Repeat:
---- example.sh
#!/bin/sh
gen_forward_conf() {
echo "# Generated by $self"
echo "forward-zone:"
echo " name: ."
for forwarder ; do
if expr "${forwarder}" : "^[0-9:.]\{1,\}$" >/dev/null ; then
echo " forward-addr: ${forwarder}"
else
echo " forward-host: ${forwarder}"
fi
done
}
gen_forward_conf 192.0.2.0 127.0.0.1 2001:db8::1 ::1 FE80::1 localhost HOGEHOGE
exit
---- example.sh
