Iii. IP Address
In a routable network layer protocol, the protocol address must contain two parts: the network address and the host address. The most obvious way to store this information is to use two separated domains. In this way, we must
Subnet division definition: Internet organizations define five IP addresses, which are A, B, and C. There are 126 Class A networks, and each class A network may have 16777214 hosts, which are in the same broadcast domain. It is impossible to have so

Preface : now engaged in the design of embedded products, many are based on TCP/IP, the requirements of the development of equipment to access the WAN for remote setup and access, which involves the principle of routing and the use of routers.
Compute related addresses by IP address and subnet mask and operations
When you know the IP address and subnet mask, you can figure out:
1, network address
2. Broadcast Address
3. Address range
4, the network has several hosts
