   There exist databases from allocation of addresses to service providers   
   which include the geographic coverage of the allocated address blocks.   
   My Linux systems have a package named GeoIP-GeoLite-data installed,   
   containing these databases. As well, there are command line tools in   
   GeoIP and C APIs available in GeoIP-devel.   
      
   Oftentimes, the result is quite wrong. I get 90+% of my Internet access   
   via AT&T hotspots. AT&T uses CGN (carrier-grade NAT), one effect of   
   which is that my apparent address as seen across the Internet depends on   
   where my connections through AT&T exit the AT&T network into other   
   providers. As a result, web searching for "what is my ip address" gives   
   me links to sites that are happy to tell me all about myself, among   
   which are their guesses for location; at the moment, depending on which   
   guess I read, they think I'm in either the Bronx, NYC, NY or Hartford,   
   CT. I'm actually northeast of Pittsburgh.   
      
   VPNs destroy geolocation. When I am traveling and using a VPS I rent,   
   running a VPN hub, the appearance is that I'm in Dallas. I haven't been   
   physically in Dallas in decades.
