 ## Changelog
 
-**2014-01-2-02**
+**2014-02-21**
 
-- Changed default IP check site to ifconfig.me
+- Added support for IPv6
+- Added support for config files
+
+**2014-01-02**
+
+- Changed default IP check site to ip.dblx.io
 - Added a switch to use _drill_ instead of _nslookup_ because FreeBSD 10 switched from _bind_ to _unbound_ 
 - Renamed _$HOSTNAME_ to _$DOMAIN_ to work around potential conflicts with _$HOSTNAME_ that's set by the host itself
