Add the option to the "Delete this account" section.

[User2]

Add the option to the "Delete this account" section: delete all personal data (ip address, email, etc.).
If the administrator needs to save the ip addresses and email, then let him leave them.
If personal data is not needed, then let it be deleted.

[Arantor]

The IP address should be kept for a period of time as part of a general digital strategy around preventing abuse to the system.

It is not unknown for someone to request deletion, have their account deleted and then return to cause trouble. Having IP addresses is a critical measure of being able to identify such cases.
