: Can somebody explain me what this means, and how to take care of this?

It simply means that there is no reverse DNS listing for the IP
address 63.162.216.21.  For example:

$ nslookup 63.162.216.21
Server:  localhost
Address:  127.0.0.1

*** localhost can't find 63.162.216.21: Non-existent host/domain

In other words--it's not a problem.
