This fixes a bug introduced in
https://github.com/coredns/coredns/pull/6547 which resulted in the zone
being added to IPv4 addresses. This bug results in a failure to start
when binding to an interface with a link-local IPv4 address assigned to
it, with the following error:
$ ./coredns -conf=/etc/coredns/Corefile
maxprocs: Leaving GOMAXPROCS=4: CPU quota undefined
lookup 169.254.1.1%dummy0: no such host
