IPv6 plan for multisite corporate

[Eric Vyncke (evyncke)]

Several US companies (including my employes) simply use the same ARIN prefix everywhere and inject local routes at each WW locations. As long as the prefix length is short enough, there will be no issue about routing or about RIR.

    Hi,
    one of my customer is a US corporate with offices literally on 5 continents and 
    one datacentre. Offices are connected each other and to the datacentrevia MPLS, 
    each office accesses the Internet via local ISP.
    
    Since they asked me to start planning for IPv6, my idea was originally to buy a 
    netblock from ARIN (maybe a /40) and use it for the offices (each office has 
    many different IPv4 networks).
    
    My concern is: if I buy a netblock from ARIN and use it in every office, how can 
    I handle the access to local ISP?
    
    I thing I should NAT the netblock of each office to handle the routing, or is 
    there some other way to do so?
    
    Thanks!
