sudo: unable to resolve host

I ran in to the weirdest error today.   “sudo: unable to resolve host”. I got this error even running as root which was the really weird part.  I was especially confused because I have been running Linux as my main OS for the better part of 10 years and have never run into this issue. Turns out the solution is very simple and almost elementary however I decided to make a quick post about it.
