Malicious DNS address

[ITShore]

Hi Buddies,

     Could help me figure out what is the meaning of these logs in my router?

 

I'm worried that this could harm my network.

Thanks.

What makes you think they are malicious? Log messages like that are normally indicators that a session through a router (especially a CUBE router doing SIP trunking) required a DNS lookup.

Hi Marvin,

Because of the doubt, I tried to check on the internet what was the meaning of the log message until I found one that gives me an idea to suspect that it was a malicious one.
But, since you gave me a good answer, it's now clear that the log message has nothing to do with cyber attacks.

Thanks, Marvin.
