Is it possible to buy a unique ip?

Question

Computer networks

I rented a VPS with the ultimate goal of hosting sites on different ips.
Where I bought a VPS, there is an opportunity to buy an additional IP address for $ 2, but it differs from the main one only in the last digit, for example :
1.1.1.18
1.1.1.34

I understand it will be the same, only the last digit will change.
The question is, is it possible to buy IPs that are unique in terms of the first digits, or does it not work that way?
My goal is to host sites so that Google does not understand that they are on the same server, for this I dig in the direction of buying IPs, but if only the last digit changes, then it is obvious that the sites are on the same server.

Answer 1

if you want different addresses, it will be easier and cheaper to just host from different providers. or from one, buying cars in different locations.
