 ## Topology
 
 You can implement this in two ways:
 
 * Use a custom backend-service to do this lookups

+   [Go-based binary](https://github.com/superstes/geoip-lookup-service/releases/tag/1.0)

 * UNTESTED: Use the [resty-maxminddb LUA library](https://raw.githubusercontent.com/anjia0532/lua-resty-maxminddb/master/lib/resty/maxminddb.lua) to query the MMDB databases directly from LUA

+You can easily log the GeoIP variables:

+```
+http-request capture var(txn.geoip_asn) len 10
