Bad naming resolution.

Hello,
I am working with some cpanel servers, and last week, I've started facing a weird problem.
when I ping nothing, I gen 127.0.53.53 as an answer:

 ping nothing
PING nothing.off (127.0.53.53) 56(84) bytes of data.
64 bytes from 127.0.53.53: icmp_seq=1 ttl=64 time=0.064 ms
64 bytes from 127.0.53.53: icmp_seq=2 ttl=64 time=0.058 ms

I've checker my resolv.cof and it's ok

cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 8.8.4.4

I wanted to know if someone else is facing a similar issue and found a workaround or a solution.
All I've founded is the following Link icann.org/news/announcement-2-2014-08-01-en but I couldn't figured out, how to fix it.

Thanks in advance!!.

I wanted to add, that also in one of my servers. when do the same ping, instead of
127.0.53.53 the answer I get is 127.0.0.1

Thanks!

Hello,

Do you notice any custom entries in your /etc/hosts file?

Thank you.

Hello Michael,
Sorry for the delay in my answer, the last weeks had been very complicated for me.
Yes, I have a few custom entries, as an example

x.x.x.x server.example.com
(being x.x.x.x the server ip address)
and a couple of entries for another servers
y.y.y.y another-server.example.com

Best Regards.

Juan

Hello,

I recommend reaching out to your data center or hosting provider to determine if that behavior is by design if you have no entries in /etc/hosts that correspond to the "nothing" hostname.

Thank you.
