Join Mark Jacob for an in-depth discussion in this video How to configure and verify an IP address, part of Learning IP Addressing.
Imagine you're hearing a story, and the story starts with, "You are the network admin." Well, hopefully you are. In this case, if you are the network admin, you may be faced with a choice. Well, I either have to decide to configure static addresses or dynamic addresses. The choice may be made for you. I just want to do a brief demonstration of how to actually go about doing that. Fairly simple, here. If I launch my control panel, I'm going to get into network and sharing. Change adapter. Whatever digging down you have to do on your operating system, depending on where it's hidden, I'm getting to the local area network connection and going to properties. Finally, I'm down here, and I'm concerned with IPv4, so I'll click on that.
And let's say I want to configure a static IP address. I would actually type it right here. Let's say 10.1.0.217, for example, with a mask of 255.255.0.0, and it can be whatever you're using in your organization. In this case, I'm using an RFC 1918 address, a ten dot. You could be using 170.216s through 31s. Hopefully not 192.168 at work. Let's go default, gateway, 10.1.0.1, and I'm just going to leave the DNS server blank. But I'm going to type that and say OK. Now, if I want to verify that what I've typed is actually there, if I can open up a command prompt—and I'm going to go ahead and run that as an administrator just so I don't get challenged with unnecessary questions—and I'm going to do a command: ipconfig/all, which by the way, I don't need a space there, it'll still work. So if I scroll up a little bit here, focusing in on the changes I just made, I have a subnet mask of 255.255, which is what I typed. I have an IPv4 address of 10.1.0.217, which I typed. And DHCP enabled, no. In other words, statically configured, I am not counting on the DHCP server to configure my network. If I want to change that, I'll click back on my local area network connection, go to properties, and come in here to the IPv4, and I'm going to change it back to the way it was before. Obtain the IP address and the DNS server information automatically. Say OK. Then I'm going to go back to my command prompt, and let's type that same command again: ipconfig/all. Scroll up. Now, DHCP enabled says yes. Oddly enough, you'll probably be figuring out behind the scenes, I looked to see what my address was before I typed the static. Nevertheless, it has been configured via DHCP, it's been dynamically configured, with 10.1.0.217, 255.255.0.0 mask. So this is how you easily tell, "Is this machine set up to be statically configured or dynamically configured?" You can look here. DHCP enabled, yes, or I was going to say in the property sheet of your local area connection, I go to IPv4, and here, again, it'll tell you if it's set to automatically or use the following address. So like I said, it's not a very difficult thing to figure it out, and it could be, again, you are the network admin, you're going to make that decision. What type of IP addressing are you going to be using in your organization?
