RE: Assigning IPv6 /48's to CPE's?
I'm fully aware of HD ratio thanks :)That's 281,474,976,710,656 /48 customer networks. It's 16 million times the number of class C's in the current IPv4 Internet. Am I just not thinking large or long term enough?
My point was to give a rough approximation of the size difference here, not to talk about the specific numbers.
I'm not sure what your point is here. I'm not remotely trying to argue this.Basically, this recognizes that IP networks are not flat piles of pebbles, but have a hierarchical aggregation structure in them. At each level of aggregation, you have to do a fitting exercise, where you fit what you have into a power of two sized block. If you have 5 subnets that need to be aggregated into a single higher level subnet, then you must use 3 bits of your subnet hierarchy, even though those 3 bits could be used for as many as 8 subnets.
You made a point about HD ratio-
80% HD with 48 bits of network address still gives us
300,000,000,000 /48 networks (unless my math is very wrong). Again, I'm not sure how we're going to use that up in 50 or 100 years, but I'm sure history will prove me a fool.
