Activity based on IPv4

Hello Network Administrator or Network Technician.

In this tutorial, we will learn about activities based on IPv4, that are:
1. Determining the network address (NA)
2. Determining the host address (HA)
3. Determining the broadcast address (BA)
4. Determining the first usable address (FUA)
5. Deteriming the last usable address (LUA)

If you given the host address, then the task you might need to accomplished are:
1. Determining the network address (NA)
2. Determining the broadcast address (BA)
3. Determining the first usable address (FUA)
4. Deteriming the last usable address (LUA)

And the question is this valid:
1. Is this valid network address (VNA)?
2. Is this valid broadcast address (VBA)
3. Is this valid host address (VHA)
4. Is this valid first usable address (VFUA)
5. Is this valis last usable address (VLUA)
