It would be nice as a start, but does not really take into consideration future expansion needs.
I would think that you could draw some parallels, though. Something like: v4 /16 ~ v6 /32 v4 /12 ~ v6 /28 v4 /8 ~ v6 /24 I know it we don't want to equate v4 and v6, but it may help as a guideline for the size of the customer base. -Randy -- | Randy Carpenter | Vice President, IT Services | Red Hat Certified Engineer | First Network Group, Inc. | (419)739-9240, x1 ---- ----- Original Message ----- > I think APNIC has a policy that defines the minimum IPv6 allocation > based on your current IPv4 allocation/usage.
