Internet Explorer is exclusively for Windows operating systems, however some versions of Internet explorer for mac were released back in the days but Microsoft released a communicate stating that will cease all further development of Internet Explorer for Mac and advised users should update to newer browsing technologies such as Safari browser.
Here is a portion of the statement for things to be clarified:
"On June 13, 2003, Microsoft announced that it was ceasing further development of Internet Explorer for Mac and the final update was released on July 11, 2003."
By default your iPad comes with the latest Safari browser and you should expect the same quality browsing because of its advanced features and page support.
