since this article mentions maxmind, this reminded me of when geolocation by IP address goes horribly wrong, and non-technical persons interpret the results as something to be relied upon as factual:
ISP perspective here: Geolocation by granular /24 to /20 sized block of ipv4 space is often wildly inaccurate on a regional basis. It's entirely possible for the ARIN registration (used by maxmind) to be a street address in Seattle, but serving end user ISP customers a 4.5 hour drive away in a far eastern corner of WA state.
