Nominum's DCS hands out randomised identifiers. The very latest version
has options to do things like skip certain identifiers:

      global-scope
        Ensure that bit 70 is unset in any addresses.  Only valid for
ranges
        of /64 or larger.
      subnet-anycast
        Skip the last 128 addresses in a range prefix.  Only valid for
        ranges of /119 or larger.
      subnet-infra
        Skip the first 128 addresses in a range prefix.  Only valid for
        ranges of /119 or larger.
      subnet-router
        Skip the first address in a range prefix.

    The 'iid-skip' field is only settable on non-prefix-delegation IPv6
    ranges.

Regards, K.
