Which networking protocol is used to assign IP addresses dynamically to devices on a network?

Correct answer: DHCP. DHCP (Dynamic Host Configuration Protocol) automatically gives IP addresses to devices.

Background: A router usually acts as the DHCP server at home.

• FTP: FTP transfers files.
• HTTP: HTTP transfers web pages.
• SMTP: SMTP sends e-mail.

Did you know? Without DHCP, IP addresses would have to be set manually.

Memory trick: DHCP = Dynamic IP.
