[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] iSCSI: question about numeric IPv6 addrWhen 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, Bill
