query re IPv6 URL format

[brian@hursley.ibm.com (Brian E Carpenter)]

Hi,

Has anybody implemented a Web browser that accepts IPv6 numeric
addresses as part of a URL, and if so what format did you use?

(to be clear, I am after the IPv6 equivalent of
the existing URL format such as http://194.196.110.160/~bc/ )

(also to be clear, the RFC 1884 syntax will break existing
browsers)

  Thanks for any info
