There is typically a 1-1 mapping.  In other words, a given letter is typically announced out of the same set of locations.  This is subject to change at any time based on various operational circumstances.

All locations are both v4 and v6 enabled with one exception: our regional platform (aka RIRS), which currently supports b.gtld-servers.net.  Some regional providers only support v4.

    I could contact Versign's customer service, but I think I'll just ask
    here. ;)
    What kind of mapping is there between the IPv4 and IPv6 addresses for
    any given letter? Strictly 1-to-1?
    Also, does each site have both IPv4 and IPv6, or is it possible for a
    letter to only have IPv4 (or IPv6 in theory) at some locations?
