Re: proper IP4/CIDR format

2004-06-11 08:45:03
What is the standard? Is the shorten format allowable?  I didn't see any
short example in rfc1812.

Thanks

Is the specific domain SPF policy IP4/CIDR setup incorrect?  What is the
proper IP4/CIDR format for the above?

The BNF in the SPF spec does not make allowances for short IP
addresses like X.Y.Z/19.  If I recall correctly, the M:S:Q Perl code
will accept it, other implementations probably follow the spec.
