RE: iSCSI: Decimal encoding - why 64 bits ?

[Robert Snively <rsnively@Brocade.COM>]

The most common example would probably be the
IP address, which is a binary value.
It is often presented
as four separate decimal numbers for no reason
I can think of, except perhaps a feeling that
hexadecimal numbers were somehow less user
friendly for inexperienced users.

See RFC 0790 and RFC 0791.
