Description NARUSE, Yui 2010-12-21 18:03:31 PST 
For IPv6 address, URI will be like http://[2001:240:629::6]/foo.html.
On IE and Firefox, when open the URI, window.location.hostname will be "2001:240:629::6".
But Safari 5.0.3 (6533.19.4) and Chrome 10.0.612.3 returns "[2001:240:629::6]".

Mozilla explicitly says remove brackets from hostname.
https://developer.mozilla.org/en/window.location

I think, it is because hostname means DNS name.

HTML5 doesn't say about this yet.

The url spec went with adding the brackets:

So I think this bug report is invalid these days.

Indeed.
