IPV6 maximun number of subnets

---

Hey ITPRO.TV
First I would like to say that I love your product.
My question is about IPV6 subneting. I was watching this topic on the accelerated CCNT course and I got the impression that since subnets in IPV6 are identified in the 4th field, does this means that only 65,536 subnets can be allocated in any given organization?

@Jose-Linares,
Each Regional Internet Registry is allocated /23
Each RIR will allocate a Local Internet Registry (ISP) a /32
Each ISP will allocate to a customer a /48
Each Customer will divide the /48 into /64 subnets for themselves which allows for 65,000+ subnets with 2^64 (18,446,744,073,709,551,616) number of hosts per subnet.

So yes you can say "only" but the size of each subnet is insanely larger than the entire IPv4 address space as currently used. Put differently, "Only" 65,536 subnets is a meaningless limitation. :)

Glad you like the shows and thanks for being a member!

With no further addition to post, I will mark this as solved.
