Even if SEO hosts have different IP's, servers etc.. DO NOT purchase SEO hosting. Google will sooner or later discover the host. The discovery does not have anything to do with where the servers are located but because the company is advertising itself as an SEO host. There would be a number of people using SEO hosting on the same servers just like you which means 50 - 100 PBN's using the same variation of hosting. That is such a red flag. I don't know why people even bother with SEO hosts.
Instead use smaller hosts. Best way to do it? google "hosting china" "hosting india" "hosting germany" "hosting greece" and make sure you find local suppliers. Double check with the providers where their servers are located. Some companies might be in different parts of the world but their servers are located in the US, don't go with those. Your goal is to get geo location IP variation.
