Hello,
I’m trying to figure out how wildcard mask works if i want to deny or permit the addresses within a subnet,for example, in the subnet 172.30.16.0 to 172.30.31.0 I know the wildcard mask is 0.0.15.255,ok but how is it able to know the range of addresses within that subnet? is it because the addresses within that subnet all start with the same binary digit? and if so why it doesn’t work in subnet 172.30.80.0 to 172.30.95.0? can sombody please give me a brief explanation on wildcard masksand how they work!
Thanks!
MD
