If you have an OS with a new enough version of BIND, you can scrape by without using any 3d party DNS services. Have a gander at https://kb.isc.org/article/AA-01149/0/Using-the-GeoIP-Features-in-BIND-

NSONE is another DNS solution which may be useful. They have GeoDNS as well but also have a data source method which can influence results. You can hook up some existing solutions (server monitoring f
