DHCP is a protocol that automatically assigns IP addresses to devices on a network, so users don’t have to configure them manually.
Why it matters:
- Saves time and prevents conflicts by ensuring devices get unique IP addresses.
- Without DHCP, IT staff would have to configure every device by hand.
- Home routers use DHCP to assign addresses to laptops, phones, printers, and more.
Pro tip: Sometimes when you see “IP address conflict” or can’t connect to Wi-Fi, renewing your DHCP lease will fix it.
