Correct. Your internal addresses are (likely) a non routable subnet as shown by @gsmith… so they would not have entries in the GEOIP table. If you wanted to, you could build your own tables with coordinates for your internal addresses… Not sure that is the most efficient way to go about it… but it IS possible…
@tmacgbay If this is internal, chance are ( hoping) @Laale have a DNS server you can get the static IP Address and create that lookup table, I was think something on the line of
