There are lots of different versions of Internet Explorer, and while all but version 11 are considered the "latest" version; we've included some user agents for the older versions of Internet Explorer here, just for reference.
The user agents here are the most basic and straight-forward versions for Internet Explorer. Internet Explorer was fairly prone to having extra fragments in it's user agent; either from the various versions of .NET that were installed or from various toolbars and addons which were installed. We haven't included any of those fragments here; choosing intead to keep it really simple.
You can explore our huge listing of various Internet Explorer user agents to see the different variations of user agents.
Our Web Browser/Operating System Version Numbers API endpoint will provide you with the latest user agents for all sorts of popular web browsers and operating systems.
