Document Summary

Calculating network /broadcast address in binary method: example1. Step 2: count the number of 1s in subnet mask: ans here is 21. Step 3: copy 21 bits from ip address for both network address and broadcast address. Simply copy the decimal ip value (130. 192 in this example ) on that octet to both network address and broadcast address. Calculating network /broadcast address in binary method: example2. Step 1: convert both ip and subnet mask to binary. Step 2: count the number of 1s in subnet mask: ans is 26. Step 3: copy 26 bits from ip address for both network address and broadcast address. Step 4: fill up the rest of the network address bits with 0. Step 4: fill up the rest of the broadcast address bits with 1. Step5: convert the network address and broadcast address to dotted decimal.
