Netmask Ordering Clarification
Posted on 2003-11-17
The subnet mask 255.244.0.0 creates the following subnet host ranges on the 10.0.0.0 network:
10.0.0.1 - 10.31.255.254
10.32.0.1 - 10.63.255.254
10.64.0.1 - 10.95.255.254
10.96.0.1 - 10.127.255.254
10.128.0.1 - 10.159.255.254
10.160.0.1 - 10.191.255.254
10.192.0.1 - 10.223.255.254
10.224.0.1 - 10.255.255.254
This was an answer to a question i had earlier attempted. (i had to get it wrong :( )
What i don't understand is how one gets to know that there will be 8 subnets out of the 255.244.0.0 subnet mask.
I do know that the subnet mask 255.244.0.0 can have 2^21 hosts from the binary notation,
but how one can relate that to 8 subnets is not getting into my head.
I did notice that the last subnet (10.224.0.0) starts with 224, what has it got to do with 255.244.0.0?
Could someone please help me understand the above netmask ordering answer?
