Yes, we do provide IP geolocation. When adding the Address field, the Default country setting is set on autodetect. This means that we will autodetect the IP of your form visitor and automatically fill in the Country subfield on the form.
If you need to display a certain country for all your form visitors, go back to the Form Editor and select the Address field. On the left-side panel, under the Options section, select the Default country dropdown and set the country of your choice.
