All,
I understand the / notation for masking, but here's what I don't think I have a full grasp on.
Suppose we have a /64 network of 2001:1000:1000:1000::/64. That leaves 2^64 for the amount of hosts or allows for breaking this block further into smaller networks. Now here's where I don't understand. I've seen examples online about /65, /66, /68, /69.
So for example:
2001:1000:1000:1000:C000::/69
How do the individual bits break up within the block?
I understand if the above was /80, but it doesn't seem like every example that I've seen is consistent with even 16 bit calculations (or even 8 bits for that matter).
Thanks!
HTH,
John
