Looking at the code this module doesn't have any exceptions at all so, this doesn't have an override IP address written in.
A custom made GeoIP locking module could be written by a consultant if you're willing to pay for one,
If so email firstname.lastname@example.org requesting the list of independent consultants.
The IP filtering/GeoIP filtering options are a bit elaborate and don't allow such fine grained setups with the current version of the plugin. I'm willing to extend functionality on a consultancy basis if somebody will need something more complex, like @gupta.ravi0709 above this post. The current version allows rules in the sense of "allow from all, except from [list of rules]" or the reverse "deny from all, except from [list of rules]".
