Adding a UNC path containing an IP address as a Trusted Location in Office 2007/2010

If you try and add a network share/UNC path to the 'Trusted Locations' in Office 2007/2010, it will give you an error ("The path you have entered cannot be used as a Trusted Location for security reasons.") if the path you are adding contains an IP address instead of a hostname, e.g. \\10.10.10.1\share. You receive this error even if you have checked the "Allow Trusted Locations on my network (not recommended)" box. Apparently you are only able to add UNC paths, e.g. \\hostname\share.

There appears to be a very simple workaround to this - simply open up Internet Options and add the IP address to your 'Trusted Sites', (file:IP address). Sites listed in your Trusted Sites seem to also be treated as Trusted Locations in Office.

UPDATE 17.06.2014
As mentioned in the comments, this is how to get to the Trusted Sites tab in Internet Options:

Open Internet Explorer --> Settings --> Internet Options --> Security --> Zone: Trusted Sites --> Sites 
or
Open Control Panel --> Internet Options --> Security --> Zone: Trusted Sites --> Sites

    Thanks for the tip, googled "cannot add trusted location by ip address" and this addressed my challenge. thanks for your blog.

    The "captcha" requirements are ridiculous! I think a robot would do a better job than I at reading these things.... 5 tries to get one through!

    This is GOLD! I have been struggling to fix this on our network for the longest time. I want our users to get the warning from Internet docs but NOT from local docs. This secret needs to get out; mind if I share this on FB?

    Thanks again!

    Just in case you struggled to find where to add your IP as per above.
    Open IE --> Internet Options --> Security --> select Zone: Local intranet --> Sites --> Advanced and then you can add file://IP Address
    Tip works for me! Thanks J.G.
