All looks good to me, some really trivial suggestions:
1/ Could you make google maps default to hybrid mode? I think that looks cooler 
2/ When no city information is found I get two '-' in the title, which is a bit weird: e.g.
123.45.67.8 - Admin User - - Australia
3/ Change this "By default Moodle uses free online NetGeo (The Internet Geographic Database) server to lookup location of IP addresses, "
to start with: "By default Moodle uses the free online NetGeo"?
4/ Change this "You can either buy commercial version or use free version."
to "You can either buy a commercial version or use the free version."
(assuming there is only one free version, I can't find the page listing them )
5/ Is this string just short so it fits under the image?
"NetGeo server used, it is recommended to install local copy of MaxMind GeoLite database."
If not, we could say something longer e.g.:
"NetGeo is currently being server used for geographical information, it is
recommended to install local a copy of MaxMind GeoLite database for more
accurate results."
sending fresh patch, needs testing
