IP addressing structures and functions
- [Instructor] Now let's review the required IP addressing components that we're going to find in a typical computer on the network. And we know the most important and the one we focus on is the IP address itself. Remember, this is identifying our network and our node ID. And here we see a 192 168 0 110. Example of an IP address. Next, we have a subnet mask. It's the job of the subnet mask to indicate what bits in the IP address identify the network and what bits identify the host portion of the address. Here, you can see a subnet mask of 255.255.255.0. And it sure does mean just what you think it might, the network is 192.168.0, and our host ID is 110. So you notice what's happening here. Everywhere we have the 255 in an octet, sure enough, that represents a portion of our network address. And then where we have a zero is our host identifier. So the mask of 255.255.255.0 indicates that we're on the 192 168 0 network.…
