IP localization: ip-> location mapping is fixed over time?

I manage a web platform and want to get statistics on where my users come from. I can save the remote IP address, and I know that there are localization services that display the IP address in geolocation.

How to do it? Are there fixed tables, which IP address was specified in which region?

Do I have to request a match at the time of access, or can I request it in a few days / months / years? In other words: Is the mapping from IP to location fixed or does it change over time?

The mapping from IP to location changes over time. I read that databases change by 5% every month, although it’s hard to find out if they really change so much or if database providers are more likely to sell their updates. But it is a fact that these databases are changing. Therefore, you should get the IP address location as soon as possible, at least not later than a month after you have captured the IP address.

If you want to keep demographic data, you must save country information obtained in place of the IP address because it may change from time to time.
