Therefore, if a Class A IP Address such 50.10.20.1 used by itself without Network Mask, how the computer would locate or identify its network portion?Īnd where this IP Address might be located in the world if the network portion can’t be identified? Hence, even Routers that use Internet Routing Protocols won’t be able to route without knowing the Network portion. When Classful Networks were created as mentioned under Understanding IP Addressing System, Internet Protocol and Internet Routing Protocol needed a way to locate the Network portion of an IP Address. Network Mask or Netmask for short, helps Computers locate and identify where the network portion is, hence, the Host’s portion at this IP could be located as well.īinary Class A Network: 0000000 1.00000000.00000000.00000000Ĭlass A Netmask: 11111111.00000000.00000000.00000000
TIP: Identifying the network’s portion will automatically identify the host portion as well. If an IP Address meant to identify a Network device on a particular Network, then the Netmask is meant to identify the Network’s portion of this device.

If you are using Windows Machine, Network and Broadcast Addresses configured Automatically for you. Note: Mainly, the minimum 4 pieces required for IPv4 TCP/IP to function are: IP, Netmask, Network, and Broadcast Addresses.
After A, B, and C Classful Networks have been created from the One Big Pie of IPv4 Space, the IP Address in each Class needed 2 logical portions to work:įor an IPv4 Network Device to function properly, 6 things needed:
