Re: [v6ops] Update of draft-vf-v6ops-ipv6-deployment and IPv4 exhaustion

[JORDI PALET MARTINEZ <[e-mail]>]

Each RIR has its own policies, developed by the community. They are close, but not necessarily matching 100%.

In some case, you need to announce all them, or only a % of what you're using now, unless you can justify that they are being used in private networks, etc., etc. Policy can also mandate you announce it within a certain period of time.

Also remember that there is space not allocated by RIRs (legacy space), which is not necessarily subjected to those policies. Again, it depends on the region and if you have signed a contract with the relevant RIR.

Yes, private networks should use RFC1918 space, but sometimes even network 10/8 is not enough, or you can find other justifications, accepted by policies for allowing you not to announce the space.

Not so easy! Legacy space + 5 different set of policies and not all the RIRs ensuring 100% (and all the time) compliance with the policies.

    In that sense, maybe there is a rule at RIRs that mandate the ISPs that 
    received IPv4 blocks to actually use them right away?  Or are RIRs 
    allowing ISPs to not use the IP blocks immediately?
