The registries (including IANA as their root) should provide just that, a place to register the use of number resources to avoid collisions. I'm thinking that "private" number spaces should probably be used advisedly if not deprecated outright. RIR's are taking heat (or some finger pointing atleast) for allocations

A prefix doesn't have to reside in this beast called 'DFZ' for to be used. There is (atm) no need for one to announce the address space used by their cool chocolate factory machines, but maybe in the future one might want to do it to be able to monitor from the comfort of ones home. Thus the address space does need to be globally unique.
i rant, yet again.
what is this "the" public routing table? where does one get it? in my 25 years of networking I have NEVER seen it.
Have you seen the moon? Touched it? I still can't be convinced that pluto exists, I haven't seen it, but it appears to be there ;)
i am convinced that it is a fictional as the "public" Internet. or the "DFZ" ... they do not exist, except in the fevered imaginations of marketing droids... and the virus is more virulent than the H5N1 strain. Note that it affects normally sane engineers who KNOW better.
Well I apparently have a lot of nasty viruses floating around in my body at http://www.sixxs.net/tools/grh/dfp/ I used "DFP" with which I mean: "Default Free Prefix, a prefix routed without having any smaller prefixes covering it. Removing such a prefix will make the prefix unreachable." DFZ would be the group of all DFP's.
back in the SRInic days, there was the "connected" and "unconnected" databases. ... to mark prefixes that were connected to the ARPAnet and those that were in "private" networks, like CSnet, NSFnet, and enterprise networks. Tony is right in this respect, RFC1918 space is a feeble attempt to get around/past the lack of address space that became apparent in IPv4 ... with IPv6, there is no real reason to try and recreate private space (leaving aside renumbering)
Indeed.
IMHO, assigning globally unique prefixes to those who utilize IP protocols, regardsless of whom else they choose to "see" via routing is the right course. every other attempt to split the assignements into "us" vs. "them" has had less than satisfactory results.
Absolutely. Address space is there to address hosts and thus should be made available to places that have a hosts. The only issues at a certain point will become routing table size and that is the new problem to fix, there is now "enough" address space. (Taking into consideration that 2000::/3 is only 1/8th of the total IPv6 address space and that we can peep up 8 times before it runs out :) Greets, Jeroen
