Classless Inter Domain Routing aka CIDR notation means you have to apply a bit mask for the number of bits after the slash so in our example 184.108.40.206/26 that means 26 bit bit mask.
# of valid IP addresses 2^(32-n)where "n" is the number after the slash
- 220.127.116.11/26 = 2^(32-26) = 2^6 = 64 valid IP addresses
- which are: 18.104.22.168 to 22.214.171.124
