Back in the 90s, I had a Windows--
I think it was Windows NT4, server on this huge laptop.
And back in the day, believe it or not, not every device
came with a built in wireless adapter.
So I was at a big IT conference.
And they were renting out network adapters
that were wireless.
And so I thought, this is great.
You know, it's cutting edge stuff.
So I rented one, plugged it in, and then I thought to myself,
I wonder what would happen if I turned on my DHCP services
on my Windows Server.
I wonder if I could hand out my own IP addresses, and then WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
I wonder if I could hand out my own IP addresses, and then
my own default gateway, my own DNS servers.
And the answer is yes, it was pretty easy to do.
Now, whether it's brought in maliciously or innocently,
we don't want rogue DHCP servers cluttering up our network
and causing outages of service.
So to solve that, we can use a feature called DHCP snooping.
And we'll continue the conversation about what it is,
and how it works, and how to configure it as we go
through these videos together.
So I'll see you, my friend, in the very next video.
