DHCP and DNS.

When you connect to Wi-Fi and open a website, everything just works — but only because two critical systems are working behind the scenes: DHCP and DNS. DHCP gives your device an IP address so it can exist on the network. DNS translates human-friendly website names into real network destinations. Remove either one and the internet breaks: ❌ No connection ❌ No websites ❌ No cloud, no AI, no online activity If you want to build real cybersecurity skills, you must understand how devices join networks and how names turn into destinations. These aren’t background services — they are the foundation of the internet. This video explains why DNS and DHCP are essential and why every cybersecurity professional needs to understand them.
