I would be extremely interested if others on the list support this type of 
address space hijacking. The only public instance of this that I know of 
is WIANA http://www.wiana.org which has hijacked 1/8.

Also, if other organization want to hijack IANA addresses to ensure global 
uniqueness, I think that it will be necessary to maintain some sort of 
alternative registry since many of the companies involved may connect 
their internal networks to more than one network using hijacked address 
space. It would not work if two organizations hijack the same block. 

I work for a company that operates a global network connecting companies 
in the financial services industry and we use registered IP addresses to 
ensure uniqueness. We have also considered hijacking the 126/8 range 
however I think I've managed to get that idea sidelined for the 
foreseeable future. Basically, none of our registered space is announced 
on the Internet although our network is connected very tenuously to the 
outer edges of the Internet.

Of course, if there is support for address space hijacking, we may have to 
review our position.
