ie 11 fails with 'IE Security detected that the URL and the configuration link to not match

HI,

I Have a user that is using IE 11 and is getting the following error:

IE Security detected that the URL and the configuration link to not match. Please use the URL as configured.  Is and IP based URL. On IE 10 we get a similar message, but as soon as we add it to our trusted site and switch to compatibility mode the issue goes away.

For example http://10.10.10.180/xxx/iafwebsite_810/

What would be causing this issue?

Any help would be appreciated.

Thanks,

Trish
