Hi, Dino:
1) " ... but overlay routers do not drop packets to/from
240.0.0.0/4 addresses. ... encapsulated packets ... ": For the
first part, correct. All SPRs do similarly, because the entire RAN is an
overlay network, although appears as a private network to the Internet
core. For the second pat, packets running around a RAN are using the
basic IPv4 header. There is no encapsulation, at all.
2) Re: Ur. Pt. 3): Yes, pieces of EzIP ideas and concepts have been
around here and there. What EzIP does is to put them together in a
concise and consistent manner to create a new networking landscape.
I look forward to your comments on EzIP.

Internet practice of listening for router availability announcements followed by dynamic mesh
routing. Since (most of) current Internet routers drop packets with 240/4 addressing, a group of
people can communicate utilizing 240/4 as long as they can find one another to establish their own
overlay network.
Yes, but overlay routers do not drop packets to/from 240.0.0.0/4 addresses. And
since those EIDs are in encapsulated packets the underlay routers don't see
them.
3) I believe that our proposal, EzIP (phonetic for Easy IPv4) may be a general purpose
solution to the above techniques that you have been discussing. EzIP approach can
establish a world-wide collection of RAN (Regional Area Networks) that
"enclose" the entire current Internet for providing parallel Internet services
with its own set of conventions and practices (pick and choose desirable resources, while
avoiding those with negative effects). Please have a look at the below whitepaper and let
me know your thoughts, so that we may close the loops.
I will have a look. Overlays with VPN support do this too. And do it securely.
Thanks for the pointer,
Dino
