Join Mike Meyers for an in-depth discussion in this video Dynamic IP addressing, part of CompTIA A+ (220-901) Cert Prep: 5 Networking.
- One thing that absolutely terrifies me…is when somebody who doesn't know much about networking…goes out to the store and they…buy one of these little home router systems,…they plug it in and, all of a sudden, it just works!…And we're all on Google and everything's great.…Well, I've got plenty of episodes that talk about…proper configuration of these things,…but part of the reason this works…is because of something called dynamic IP addressing.…On most systems today, you don't actually…type in the IP address or the subnet mask…or the default gateway.…
It just magically appears through something called…Dynamic Host Configuration Protocol, or DHCP.…Now, if you take a look at my system right here,…you'll see that I have an IP address,…I have a subnet mask, and I have a default gateway.…What I'm gonna tell you right now…is I did not enter this.…I'll prove it to you.…So, let me go into Control Panel.…So here I am, right on Internet Protocol Version 4,…let me look at the properties here.…
And look what it says, Obtain an IP address automatically.…
