5 Accounts Per IP Classification Please

I am confuse about this 5 accounts signup per ip address. Which ip is Instagram logging when I create multiple accounts? Lets say.

I Live in Country A
I signed up multiple accounts via vpn in Country B
I phone verified all my accounts using Country A area code.
I bot accounts using Country A ip address.

My confusion. I've read that you should be botting no more than 5 accounts on the same ip. Is it safe to switch between accounts using the same ip address as long as I don't go over the 5 limits? How can Instagram track what accounts associate with what ip address if it changes? I don't use proxies and my ip is dynamic. Is this going to be an issue if I am running multiple accounts?

Personally I haven't had any problems (apart from the beginning) with running 5 accounts on my real IP. At the start you might run into some problems but after a week you should be fine.

Me to didnt had any problem but to be on a safe side use can use 3 account per ip
Dont know when ig updates its policies

Usually its recommended to use 1 Account + 1 Proxy , the proxy location should match your Android Language ( User Agent ). If you login in 2 different locations quickly its high likly that instagram will reset your password or place some sort of verification on this account. To Avoid that i recommend you to create account with 1 proxy and manage the account with same proxy + using proxy location to match your phone language / location. Hope it helps
