So I ended up not posting anything.<\/p>\n<h2>The ARIN Doc<\/h2>\n<p>I continue to get questions on this topic though, and the ARIN doc is actually a tad hard to find unless you already know exactly where to look for it, so I changed my mind and decided to just post up their chart here. It goes from \/0 to \/128 and compares classful, IPv4 and IPv6 subnets with the number of addresses in each prefix size for each address type listed. Then, on the last page, it also includes a list of IPv6 prefix lengths (subnet masks) and details the number of \/48, \/56 and \/64 subnets within each one. All in all a great reference sheet to have handy when laying out IPv6 subnet plans.
