iSCSI: draft 7: IPv6 addresses

["Elliott, Robert" <Robert.Elliott@compaq.com>]

In iSCSI revision 7, section 1.2.7 (page 27) and appendix E (page 172)
describe specifying IPv6 addresses with "dotted decimal notation."

According to RFC2373 the preferred representation for IPv6 
addresses is hex numbers with colons, with a few variations:
1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are the
      hexadecimal values of the eight 16-bit pieces of the address.
2. ...The use of "::" indicates multiple groups of 16-bits of zeros.
      The "::" can only appear once in an address.  The "::" can also be
      used to compress the leading and/or trailing zeros in an address.
3. An alternative form that is sometimes more convenient when dealing
      with a mixed environment of IPv4 and IPv6 nodes is
      x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values of
      the six high-order 16-bit pieces of the address, and the 'd's are
      the decimal values of the four low-order 8-bit pieces of the
      address (standard IPv4 representation). 

I suggest that iSCSI follow these conventions.

The reference for section 11 would be:
[RFC2373] Hinden, R. and Deering, S.  "IP Version 6 Addressing 
    Architecture," July 1998.

This was mentioned on the IPS list back during revision 5:

apparently without resolution.
