> I don't think the RFCs forbid the zero address being used


RFC 1122 does: "IP addresses are not permitted to have the value 0 or -1
for any of the <Host-number>, <Network-number>, or <Subnet-
number> fields (except in the special cases listed above)."

RFC 3021 modifies this requirement, allowing the zero address to
be used for an 31-bit prefix.

Regards,
Martin
