For how long does a given ASN stay valid?

I am using the latest ASN database from maxmind

https://dev.maxmind.com/geoip/geoip2/geolite2/ .

How far back in time are these mappings valid? Do they change often (every 6 months, every 2 years)?

I am asking this because I want to know if a given ASN can be used with historical ip addresses. Can someone share some insights here?

Thanks!

There is fixed duration for the ASN update. It changes every day because of allocation and reallocation of AS.

You should always use the latest ASN with the current IP address.
