This looks like a custom code.
They use the Flexible pricing for the most accurate IP data | IPinfo.io for geolocation, the tier required to get city data is at least $49/month.
Our app JsRates (JsRates: Custom Shipping Rates - Create custom shipping rates & shipping rules with JavaScript. | Shopify App Store) can do that with some custom coding on your store front. The store front script is not part of the app feature - but we might be help you implement it depending on your requirements. If keen, reach out to customer support in the app after installing the app (with free demo plan - no commitment to upgrade to full plan before discussing your requirements and completing the setup).
