ok, cool... but they'll need to connect to remote offices? or is that just not something you all do?
2) o justification in light of 'unclear' policies for an address block of the right size. NOTE:I don't think the policies is unclear, but that could be my misreading of the policies.For me, this seems unclear: 6.5.4.2. Assignment of multiple /48s to a single end site When a single end site requires an additional /48 address block, it must request the assignment with documentation or materials that justify the request. Requests for multiple or additional /48s will be processed and reviewed (i.e., evaluation of justification) at the RIR level. Note: There is no experience at the present time with the assignment of multiple /48s to the same end site. Having the RIR review all such assignments is intended to be a temporary measure until some experience has been gained and some common policies can be developed. In addition, additional work at defining policies in this space will likely be carried out in the near future.
I always read this as 'end site' == 'street address'. So, if you have an office at 123 any st, elbonia, IN. and that gets large enough that you have 66k subnets and thus need another /48... you'd have to document the reasoning for that. If you have 12 sites though, each at different locations and were applying for PI space, it seems you'd ask for a /44 or something like that... (assuming no growth)
o will your remote-office's ISP's accept the /48's per site? (vz/vzb is a standout example here)Not too worried about VZ. Given that large content providers are getting end-site address space, I think they will have to adjust their stance.
most of the large content folks just got +/32 not PI /48's... or 'yahoo and google'. I'm not sure what Akamai's plan is, they often seem, in the v4 world, to use PA space so maybe that model works for them in v6 as well. I agree that eventually vz will most likely change their stance, but until then, and for the sites who don't have an incentive to change...
o will your remote-office's have full reachability to the parts of the network they need access to? (remote ISP's filtering at/above the /48 boundary)Remote offices aren't included in this plan.
ok... don't have them or don't plan on having them? -Chris
For the Enterprise still used to v4-land ipv6 isn't a win yet... for an ISP it's relatively[0] simple. -Chris 0: address interfaces, turn up protocols, add 'security' assign customers /48's...(yes fight bugs/problems/'why is there a colon in my ip address?" (what if you do have 200 offices in the US which aren't connected on a private network today?)-- Tim:> Sent from Brooklyn, NY, United States
