I have noticed that when I try to use the geo/search REST API method with an IP address as the criteria, the result always returns an error stating there is no location associated with the IP. I understand that might just mean exactly what it says, but I get the same error response when using the sample IP (188.8.131.52) address in the Twitter REST API documentation for that endpoint (https://dev.twitter.com/rest/reference/get/geo/search). I would expect that example IP address to return a result? I have not been able to find any IP that will return a result from this endpoint.
Is this still supposed to work? I don’t see anything in the documentation that says it’s deprecated etc. Are there any known issues with using this endpoint?
