In any case, SPF is not a router. It doesn't have anything to do with

But DNS packets containing SPF records are transported through routers,
isn't it? So if a router at a back-bone sees a packet containing an SPF
record with an invalid ip-addr/cidr-len, it will crash and the whole
Internet will collapse. :-)
