Can the same IP address be whitelisted for multiple accounts?

The IP address can be added to different accounts, but it's not supported to exist in multiple accounts at the same time. For example, account A and account B use the same server, the server IP address is added to account A, then it will be charged from account A. If account B also adds this IP address later, the IP address in the allowlist of account A will be removed and the fee will be charged from account B.
