Hi,

From the SPF-classic draft (http://spf.pobox.com/spf-draft-200406.txt):

--------
4.7 "ip4" and "ip6"

These mechanisms test if the <sending-host> falls into a given IP
network.

IP4 = "ip4" ":" ip4-network [ ip4-cidr-length ]
IP6 = "ip6" ":" ip6-network [ ip6-cidr-length ]
ip4-cidr-length = "/" 1*DIGIT
ip6-cidr-length = "/" 1*DIGIT

ip4-network = dotted-quad notation
ip6-network = conventional IPv6 notation
--------

So that's the string ip6, followed by a colon : followed by the conventional IPv6 notation, clarified a bit later on in appendix A with:

ip6-network = as in [RFC2373] [15], e.g. 12AB:0:0:CD30



Koen

Btw: the current ietf draft has the same wordings.

The current draft-ietf-marid-protocol-00.txt says on page 27:

| ip6-network = as per [RFC 3513], section 2.2,
| e.g. 12AB:0:0::CD30

Which is *not* a legal IPv6 address (the bug has been reported weeks
ago).

I don't think the spf-classic spec is being maintained anymore, but the reference to rfc2373 says enough i think?

BTW, yesterday we got a new Rfc 3849 for IPv6 examples:
<ftp://ftp.rfc-editor.org/in-notes/rfc3849.txt>

The new example in draft-ietf-marid-protocol-00.txt is
| e.g. 12AB:0:0::CD30

Maybe it should be changed in a future protocol-01.txt to
| e.g. 2001:DB8::CD30
Bye, Frank
