How do i easily convert binary numbers to decimal, vice versa. I can do with my calculator, but have no clue how to manually. Subnet is broken down into 4 parts called octets Each octet is broken down into 8 bits which are either turned on 1 or off 0. Could you help me find those? Apply this on both ip 1 and ip 3 and see that results are different. In other words, the bits on 1 in the subnet mask says where the received packet address should be the same with the local address.

Other devices present more of a challenge. If one prompts you to enter the subnet mask, you can usually use the same one as your computer.
