At this time from geo-ip data the following values are accessible

• country
• region
• city
• provider/ISP OR Organisation see Separate Provider & Organization in Visitors Log #6615
• domain
• GPS coordinates
• continent (not shown, but seems to be stored since it's acessible with segment editor?)

would be good to store and show all available from maxmind, including

• country code
• postal code
• metro code

see demo:
https://www.maxmind.com/en/geoip-demo?pkit-lang=en

once again this is the topic of always storing all raw data...

usecase e.g. making filter for postal code available afterwards even if it's not at same time integrated in segment editor...
