+iptogeo allows to know which country has a specific IP.
+It's based on data provided by AFRINIC, ARIN, APNIC, LACNIC and RIPENCC organisation.
+
+!!! These data are updated every day, so iptogeo must be recompiled every day to be up to date !!!
+
+It supports bot IPv4 and IPv6 requests.
+
+Be careful : the result is only the assigned IP by a regional regulator, but the end user
+may be located in another country. It's the case for ISP that rents IP to differents countries.
+iptogeo does not plan to replace big commercial Geo databases on this point.
+
+Two mode are available : server mode which listen for queries on default port 53333 and
+interactive mode allowing command line queries.
+
+To compile it :
+
+    make data src
