Assigning IP Addresses - CompTIA A+ 220-1201 - 2.6

If you're responsible for configuring IP addresses on a device, you know, there are a number of important parameters that you'll need to add. One of these, of course, is the IP address itself. Every device needs a different IP address. And you may need to assign these manually or configure this IP address into the configuration of the

service. So you may add for example 192.168.1.165 and now you've configured the IP address. But of course you don't have an IP address unless you also have a subnet mask. The subnet mask is used by that local device to determine which subnet it actually sits on. When we refer to an IP subnet, we're referring

to this combination of an IP address and a subnet mask. A typical subnet mask might be 255.255 255.255.0. And since the subnet mask is not something that's commonly sent across the network, we'll need to get with the network administrator for that IP subnet to confirm that we have the correct subnet mask. And if this device

needs to communicate outside of this local subnet, they'll need the IP address of the local router. This is often referred to as a default gateway. For example, the default gateway on this network might be 192.168.1.1. You'll commonly be provided with all three of these by the network administrator. And this is what will

give you the basic connectivity to communicate on your local subnet. And outside of this local subnet, there may be other parameters that you need to manually configure such as DNS server configurations, NTP servers, voiceover IP servers, and other important IP configuration parameters. In an earlier video, we talked about DHCP or the dynamic host configuration
