Perhaps this message when using /usr/bin/dig without +short might be the answer…?
;; Got answer:
;; WARNING: .local is reserved for Multicast DNS
;; You are currently testing what happens when an mDNS query is leaked to DNS
I guess the MacPorts version considers this a security issue?

One of things it does is check that other computers on our network are up by getting the current IP address for the computer by using dig to make a mDNS query (dig +short @18.104.22.168 -p 5353 hostname.local).
