Net Masks and the Subnet Calculator
Hi,
Regarding the below chart,
Which is pulled from http://www.sustworks.com/site/prod_ipr_subnets.html
Network range would be 0-255
I understand that you need to subtract the IP address of network address and broadcast so I thought it would result to 253.
Although I was told that the correct answer is 254. The subtraction was made from 256-network address-broadcase=254 is what I was informed.
I'm not sure why it gets subtracted by 256? Can someone explain please?
