PPPoE, or Point-to-Point Protocol over Ethernet, is a network protocol commonly used by AT&T for broadband connections. It encapsulates PPP frames into Ethernet frames, enabling user authentication and data encapsulation over an Ethernet network. For AT&T, users typically need to enter a username and password provided by the service, which allows them to establish a connection to the internet through their DSL or fiber services.
