How IE8 catagorises Top Level Domains

Found an interesting issue between IE7 and IE8 (and above) to do with how IE categorises Top Level Domains (TLD).

Why does this list matter? Because it controls what domains you can use with wildcards in site to zone assignments within group policy.

If your domain is on the list - You can't use it with a wildcard.

You can see what the list is by using the following URL in IE8 or IE9:
res://urlmon.dll/ietldlist.xml

Does anyone know what it is in IE10?

Thanks to the following article for helping us along the road of discovery:
