An offline utility that retrieves country information from IP-address or hostname, displays allocated IP-address blocks for specified countries, and allows for searching of country codes or countries without requiring an internet connection.

XIPL's interface is simple and user-friendly. You can quickly view IP-address blocks allocated for specific countries and even search for a country by code or code by country. This is particularly useful if you need to identify the location of a specific IP-address or simply want to know more about the countries associated with specific IP-addresses.
Overall, I would highly recommend XIPL to anyone in need of a reliable and easy-to-use offline tool for retrieving country information from IP-addresses or hostnames. It's an excellent solution for anyone who needs to work with this type of data on a regular basis, but doesn't want to rely on an internet connection.
Version 1.2.3: added option to change IP blocks notation.
