Just a reminder that if you’re going to be storing IP addresses from people who visit your site, you’ll also need to think about security measures for keeping that data safe!

Also worth mentioning that IP Addresses are considered to be personal data, personal data should be well protected!

The ruling means that data owners may need to tighten up even further their consent policies on websites.

The “weird string” you are talking about is likely a IPv6 address, this is totally normal since the world is running out of IPv4 addresses. Some ISPs handout IPv6 addresses whilst others hand out IPv4 addresses.
