The question is not entirely clear. At the moment, the accounts are doing well. Accounts from different suppliers, I do not register, but I check accounts, and also edit them before selling them using programs. I do not guarantee that the accounts will work for weeks, months, years, it all depends on Google, on how and when it determines and whether it can determine where these accounts come from, where and when they were registered and thereby determine for themselves whether they violate whether Google rules these accounts, their registrations, and so on. Accounts live and work well. If Google starts introducing updates, launching its bots or artificial intelligence, then account registrars may have registration problems and Google starts blocking accounts from some registrars, as well as those accounts that they registered earlier, but not all of course, rarely when Google delves into old registrations, but there are cases. If they tell you that their Google accounts are great and will live and work for a long time and forever, then they are deceiving you or do not understand what they are talking about. Some accounts can live forever, other registrars can be blocked at any time. Live well manually registered accounts in small batches that use a minimum of people.
What IP to use, in principle, does not matter, the main thing is that they are not spammed by their work in Google.
