really don't want to interrupt this great dialog, just one comment. don't think is about a bigger address space for routing, but rather combining 2 completely different lookup schemes.
Step1: you lookup the routing location of Mr. Smith, or Mr. Li, or Herr Meier or Mr. Dupont in a huge ID "phone book" a (secure) distributed database lookup problem, strictly overlay not a routing problem. Step 2: you insert the letter into an outer envelope with a postal-service (routable) address, leverage whatever hop to hop routing lookup solution you have at the moment scale, cost, efficiency wise. FedEx, ups etc. Lots of use cases and benefits. --szb On Jul 8, 2013, at 13:11, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> wrote: See my notes starting with HH inside.

" Dino,really? Yes - really. When you post an email like you did (and you do it repeatedly with little technical data), I have to respond that way. HH: Here is all technical detail: http://www.igi-global.com/chapter/topology-aggregating-routing-architecture-tara/77501 By our last dispute a while ago I learnt that LISP does NOTHING to ease the IPv4 And it never claimed to solve this problem. It you know what? It does help because you can use other address spaces to help the allocation of devices. So you can use IPv6 EIDs for site devices versus IPv4 addresses. Allowing more IPv4 addresses to be used for RLOCs and therefore be able to address more sites. HH: But anyone who sees that the IPv4-address is enhanced by another 4 octets locator is tempted to assume that uniqueness is provided by some unique combination of IPv4 address + locator. Just as if a postal letter is sent to some Mr. Smith, or Mr. Li, or Herr Meier or Mr. Dupont. And btw, I am not sure whether that wasn't an initial argument in favor of LISP, otherwise I would have brought up this issue years earlier. adress depletion issue (well, it rather eats up some extra addresses). While by involving the user as well as the DNS (i.e. by mapping a FQDN to IPv4 How is LISP involving the user? HH: LISP is not involving the user, that is my reproach. If there were no IPv4 address depletion issue then it would be a pro-argument not to involve the user. But a) we are used to getting WINDOW-updates every now and then, and b) by expanding the IPv4 address space by O(2^32) that pro-argument is overruled by far. (TARA would even provide an IPv4-address space extension of O(2^40) !!! ) address + Locator) the IPv4 address space could easily do for another thousand years (all it takes is to ensure that any IPv4-address is unique per associated locator) LISP-DDT prevents that for good, and you make us believe that LISP would be of any service to IPv4 ?! LISP-DDT is a database to move Map-Request around. It says nothing about how and how much address is allocated. HH: Right, sounds very innocently. But even LISP 2.0 (I guess) had once been better . The bad thing is that very very precious time goes by while (naive) people/observers trust in LISP on this respect. Because it is becoming proven in their experience. HH: I never doubted that LISP would just work as you have had it in your mind, nor that you would be able to adjust it such that it suits all existing forwarding mechanisms. Just like myself when I argued that LISP-DDT cannot work assuming that LISP were after a 4+4 octet unicast address space extension. But you let all up to NAT. This is really not a serve. I cannot parse the above.

Who is able to control these servers is able to control internet forwarding. I can imagine that the RSA would like LISP very much. Don't worry, before you traffic to be encapsulated by LISP you will use DNS...
