I suspect that the .com vs. .co.uk/.com.au, etc. is part of the country/region settings in your browser as far as IE is concerned.
In Opera and maybe Firefox (I can't recall), the server-name completion is optional and is configureable so you can tell it what extensions to try. I just tried it, and Ctrl-enter works, but after a delay, I think, because it first looked for a local machine called kisrael (as I left that option on) and then started guessing .com.

On occasion when I type just 'www.hotmail.com' at work, it takes me to
http://www.www.hotmail.com.org/. LAME.

It defaults to .com in the UK even with the regional settings on. It won't even change Favorites to Favourites.

So is it colors or colours?
.co.uk is a pretty important domain, so that's annoying, though I remember noticing in some European countries ".com" is still pretty coveted, probably often they want to be continental, not just their own home nation.
