And RFC4322.

FreeSWAN has a number of local controls whereby one simply lists the
CIDRs that one wishes to be "secure or fail" vs ones that are "nice to
be secure". Many people have implemented MESHs by distributing the
reverse DNS.

What it is missing in IKEv1 is a way to turn the host<->host tunnels
into subnet<->subnet tunnels, and that would be easy to do in IKEv2 with
the TS.
