If you get this in your email, it's a scam
purported by someone pretending to be with Red Hat, an open-source software company:
Subj: Someone tried to access your personal root server.
Someone with ip address 18.104.22.168 tried to access your personal root server.

I got the email, too. The one I got cites the same IP address as the one Z Trek reports. Did an IP search on 22.214.171.124 out of curiosity - it belongs to Merck in Rahway, New Jersey.
Now if there were only a utility to find an email sender's true identity...
