Hard to tell here’s what I find out about my IP:
=> {:country=>"United States",
:country_code=>"US",
:region=>"Tennessee",
:city=>"Nashville",
:latitude=>36.1315,
:longitude=>-86.8019,
:location=>"Nashville, Tennessee, United States",
:geoname_ids=>[6255149, 6252001, 4644585, 4662168],
:asn=>7922,
:organization=>"COMCAST-7922"}
There will be a bunch of ways that this could have false positives or negatives. Your best bet is some other solution to the problem that you’re solving with the redirect.
