• Old version: Shows nothing when resolver1.opendns.com is resolved using v6

• After my first commit: Shows v4 address when resolving happens with v4 and v6 address when resolving happens with v6

• After my 2nd commit: shows v4 address followed by v6 address on a new line.

Warning: When there is no v6 address available my 2nd commit will show ;; connection timed out; no servers could be reached and it will return returncode 9.
I could change this warning to something pretty but then it would become a really long alias (certainly because there is similar behavior when it's a system with only a v6 address)
