IPoE vs PPPoE — What's the Difference?

When you sign up for NBN, your provider will either give you a username and password — or tell you that you don't need one at all. That comes down to the authentication method your router uses to connect to the ISP's network. There are two: IPoE and PPPoE.

IPoE (Internet Protocol over Ethernet) uses DHCP to get an IP address. The ISP identifies your router by its MAC address. No username, no password — plug in and it works.

PPPoE (Point-to-Point Protocol over Ethernet) uses a login handshake. You enter the credentials your ISP provides, and your router authenticates every time it connects.

Which One Is Better?

Neither is better. They are simply different authentication methods. For most users:

• IPoE is simpler — no credentials to enter, works with almost any router out of the box
• PPPoE is more explicit — the login handshake means you know exactly when the connection is established, and you can disconnect/reconnect with a single command

Does It Affect Your Plan?

No. The authentication method has zero impact on speed, data, or price. It is purely a technical detail about how your router connects to the ISP.

You can see the connection type for every provider on their detail page. If you are buying a new router, check that it supports whichever method your ISP uses — most modern routers support both.
