Re: iSCSI: question about numeric IPv6 addr

IPV6 addresses are explicitly supported and you will find examples in the text - Julo

When looking through appendix D (SendTargets), I noticed what looks like
an IPv4-centric bit, in the TargetAddress part. Here's the text:

     Followed by zero or more address keys of the form:

       TargetAddress=<hostname-or-ipaddress>[:<tcp-port>],<portal-
         group-tag>

The problem is that an optional :<tcp-port> is ambiguous for IPv6. You
can't tell the port number from the tail of a valid IPv6 numeric address.

Turns out RFC 2732, which we site, breaks the ambiguity by stating that an
IPv6 address should be given surounded by literal brackets. i.e. something
like '[::1]'. Thus port 3260 on localhost would be '[::1]:3270'.

I'd like to suggest we add an explicit use of an IPv6 address, and also
change the wording below:

     In the above example, a DNS host name could have been returned instead
     of an IP address, and that an IPv6 addresses (5 to 16 dotted-decimal
     numbers) could have also been returned.

IPv6 doesn't use dotted-decimal numbers, it uses colon-separated
hexadecimal ones.

Take care,
