With my Computing lecturer hat on, I see no cause for concern. An IP address does not identify an individual (both factually and legally, according to case law from file sharing cases). Unless you've specifically paid for a fixed one and never use a mobile device or a different wifi network, they can change arbitrarily.
Although you are of course correct that an IP address doesn't identify an individual, on its own, it is regarded as an "online identifier" under GDPR, and "online identifiers" do legally constitute personal data.
An IP address, combined with other information, can after all be used to distinguish one person from another, and thus to identify an individual.
After all, if you think about it, a
name doesn't identify an individual. There are thousands of John Smiths, to take the usual example. But combine the name with an address, or a telephone number, or height, or birthdate, and you can tell one from John Smith from another and thus identify an individual.
The point being that "personal data" isn't necessarily data that identifies a person
on its own.
