It's possible?
speaking of IP networks in general, and the Internet in particular, although not limited to these, but also including local networks (on this side of the router)
Is there any way in which two processes/machines/even viruses can communicate other than through a domain name and an IP??
and in a certain way, the domain name has to be converted into an IP through a DNS resolution
I ask in the context of cybersecurity and mechanisms that malwares have to communicate with each other, one way is to know the IP of the C&C or the victim, and use it directly. And the other, from what I see, is to "encode" a domain type xyxyxyxxyxyx.xyxyxy.tk and use this as a bridge for the IP C&C or IP of the victim
