So, we want secure connectivity information, saying essentially that "net
X is connected to AS Y".  One option is to modify BGP-6 to carry
certificates. But this is overkill -- the connectivity information is
static, about as static as address assignment.  Why not just place it in
the DNS ? The inverse domains can be secured by DNS sec, with delegation
traceable all the way up to the IANA.  We could easily place an AS record
in that hierarchy, e.g. "*.18.in-addr.arpa AS IN 12345".  That would allow
instant checks by just looking in the DNS, and a path to escalation in
paranoia land for the security conscious.
