One of the key input vectors being exploited is the geofeed — a mechanism defined in RFC 8805. A geofeed is just a CSV file published by the address holder that says "this prefix is in this country, this region, this city." Geolocation providers like MaxMind, Cloudflare, and Google actively scrape these files and use them as a data source. The problem? There is essentially nothing to validate them. If you control a block of IP addresses — or lease one — you can publish a geofeed that claims those IPs are in Tokyo, São Paulo, or anywhere else you want. There's no verification against physical infrastructure, no cross-referencing with actual routing paths, nothing. You write a CSV, you host it, and the geolocation databases eat it up.
