Thanks. ISP’s IP is registered under an ISP, its belongs to them. DC IP is an IP belong to that DC. Actually sometimes the DC IP is blacklisted for many possible reasons, thus if it was possible to get an IP in the ISP’s IP range would be better than a DC IP. But I couldn’t get one for myself yet, and I’m not sure if I research and buy an IP with a better range, can I connect it to my VPS or not?
Tnx and bets of luck
