an IPv6 /24 and an IPv4 /24 use up the same percentage of the total address space.
How do you work that out? Please enlighten me. 2^24/2^128 x 100 is many orders of magnitude smaller than 2^24/2^32 x 100: gromit% bc scale=50 2^24/2^128*100 .00000000000000000000000000000493038065763132378300 2^24/2^32*100 .39062500000000000000000000000000000000000000000000
There are of course the same number of IPv4 and IPv6 /24s.
Percentage is calculated by dividing the number of things under consideration by the total number of things. When I used the word "an", I meant one thing. Assuming that the number of IPv4 and IPv6 /24s is 10 1/10 = 1/10 Assuming that the number of IPv4 and IPv6 /24s is 8192 1/8192 = 1/8192 Assuming that the number of IPv4 and IPv6 /24s is 2882873787 1/2882873787 = 1/2882873787 Do you see a pattern forming? --Michael Dillon
