I had a unique identifier that identifies the location of a particular website or sender. The IP address looks like a four-part numeric combination written in decimal numbers (octets) with dots. For example, 172.217.22.14 or 213.180.204.11. But as it turns out, there are a lot of myths surrounding the unique IP, for example:
A dedicated address will help protect against accidental blocking, mail ban and search engine sanctions, but in the case of DDoS attacks, it will only partially help. When one of the sites on the server is attacked, its "neighbors" suffer one way or another, even if they have their own IP.
This is why I switched to the general IP 192.168.1.1.1 login, as it is enough for me.
