This question already has an answer here:
Suppose I have these 3 IP Prefixes :
18.104.22.168/26 22.214.171.124/26 126.96.36.199/26
and I want find the aggregate prefix.
I convert each address to its' binary equivalent:
10111110.10011010.00011011.00000000 10111110.10011010.00011011.01000000 10111110.10011010.00011011.11000000
And we see that the common pattern lasts until the end of the third octet (24 digits). So shouldn't the aggregate be 188.8.131.52/24 ? Why is it 184.108.40.206/23 ?
