Hi Robert, 

If the goal is increased robustness by having addresses present from a different RIR,
wouldn't it make this whole tempest in a teapot moot if, instead of *reunubering*, you 
simply *added* a second set of IPs, but continued to answer queries on the original
addresses as well?

Is there any reason at all to unconfigure the original IPs from the servers after the LACNIC
IP addresses are added to the servers?  I mean, it's perfectly normal for servers to have 
multiple IP addresses on them, we've been doing it for decades, and IPv6 has really hammered 
home that it's normal and expected for hosts to have multiple IP addresses on them, often from 
different providers.

Thanks!

Matt

Hi Terrence,

DNS Root Server addresses from ARIN are assigned from the critical
infrastructure pool, and ARIN policy does not allow them to be
transferred to another RIR. The relevant policy section is:

8.4. Inter-RIR Transfers to Specified Recipients

[...]

Conditions on source of the transfer:

    [...]
    Address resources from a reserved pool (including those designated
    in Section 4.4 and 4.10) are not eligible for transfer.
