Can't resolve IP and unknown name/service

Recommended Posts

On the bottom, [Warning] IP address '209.126.136.5' could not be resolved: Name or service not known is displayed.

 

https://www.abuseipdb.com/whois/209.126.136.5 shows the following:

  • ISP QuadMetrics
  • Usage Type Data Center/Web Hosting/Transit
  • Domain Name cari.net
  • Country United States
  • City San Diego, California

My server is hosted by 1&1.

 

I can find no relationship between 1&1, QuadMetrics, and cari.net.

 

Why might MariaDB display this warning and this specific IP?

Yeah it was.  Since closed.  Before closing, I restarted mysql and it was still connected.  Would that make any sense?
^
What?
If you're talking about the message in the log, well yeah that's not going to disappear. What matters is whether any more of them appear.
