Or, you know, it's a personal blog: you don't, because access request IPs are part of how TCP/IP works (it's literally in the name) and cannot identify a person unless your website has a user management system and logs IPs in tandem with session id activity so that that the IP can be resolved to "a person".
This is one of those "if someone wants their IP scrubbed, they can request it, but lol no" situations: for blogs run by regular folks instead of services run by businesses, just pointing to "it's in the GDPR" is not enough. The GDPR gets a LOT of things intentionally wrong so it can go after PII-gathering-so-that-can-be-monetized businesses.
