When reinstalling MacOS High Sierra, setting root user password I have noticed strange line `dsl-201-101-1-179-sta:` before my admin username `user$`

I Googled and found references to WannaCry ransomware. Other references showed IP with Mexican DSL provider `dsl-201-100-226-146-sta.prod-empresarial.com.mx`. An example reference to security site: [https://www.vmray.com/analyses/wannacry-ransomware/report/user-sequential-behavior.html][1]

I am really not sure how it came to be but it does not matter how many times I reinstall my Mac after a while this comes up in my terminal.  I had never used windows on this computer and it was wiped securely thru disk utility before fresh install many times.
