IPoE (IP over Ethernet) is a technology for providing Internet access where IP traffic is transmitted directly over Ethernet without using the PPP (Point-to-Point Protocol). IPoE is widely used in modern broadband networks as an alternative to legacy methods (such as PPPoE) and enables simpler and more flexible access management.
Features and Differences from PPPoE
Traditionally, DSL networks used PPPoE, which required user authentication via login and password. In the case of IPoE, identification and access control are handled by other mechanisms:
- DHCP (Dynamic Host Configuration Protocol) – automatically assigns an IP address and connection parameters.
- 802.1X or RADIUS – provides additional authentication and access control when required.
The key difference of IPoE is the absence of a separate PPP tunnel. This simplifies the connection process and reduces the load on provider equipment.
Applications
IPoE is actively used by ISPs and in corporate networks:
- for broadband access services (FTTH, FTTB);
- in metropolitan Ethernet networks;
- in service provider networks for mass subscriber connections without complex configuration;
- in high-throughput networks requiring simplified operation.
Advantages
- Ease of use – no need for login and password; automatic configuration via DHCP is enough.
- Reduced equipment load – no PPP encapsulation or tunnel processing required.
- Compatibility – supported by all modern devices and operating systems.
- Flexible authentication – access control can be based on MAC address, 802.1X, or RADIUS.
- Scalability – suitable for mass connections, making it optimal for ISPs serving thousands of subscribers.
Example
An Internet service provider connects residential customers using FTTB (fiber to the building, Ethernet to the apartment). Authorization is handled with IPoE via DHCP and MAC address verification. Subscribers get an Internet connection immediately after plugging the cable into the router, without entering credentials.
