IP List Generator 2.11

by Vitaly, Friday, March 20th, 2020

Version 2.11 of the IP List Generator has been released.

What’s New

New feature: find ISO country code for the country associated with the IP address.

IP List Generator uses MaxMind’s GeoIP2 binary database (MMDB) to resolve country by IP.

Web Proxy Checker also uses this database to find the country of the proxy by its IP.

MaxMind DB Reader for Delphi

by Vitaly, Friday, October 25th, 2019

The MaxMind DB file format is a database format that maps IPv4 and IPv6 addresses to data records using an efficient binary search tree.

MaxMind provides variety APIs for lookup IP information in their database: for C, C#, Go, Java. But, unfortunately, API for Delphi is missed. MMDB Reader project solves this omission.

User Agents

by Vitaly, Monday, April 27th, 2015

“User-Agent” HTTP header allows to identify Internet Explorer version.

Look the following article to learn more about Internet Explorer user-agent strings: Understanding user-agent strings.

Pay attention to the compatibility changes in IE 11:

  • The compatible (“compatible”) and browser (“MSIE”) tokens have been removed.
  • The “like Gecko” token has been added (for consistency with other browsers).
  • The version of the browser is now reported by a new revision (“rv”) token.

Below is the list of some user-agent strings used by Internet Explorer 8-11:
