Check if your connection uses DHCP or PPPoE for IP assignment.
Hello everyone, I understand the distinction between DHCP and PPPoE. DHCP sets up connections automatically, whereas PPPoE requires using a dial-up method with a username and password to connect to your ISP. Recently, I upgraded to a fiber optic connection. My question is, which option should I pick? Or does it depend on my location? From a speed perspective, there seems to be a difference—different segments and possibly varying speeds even if that’s just perception. I’m curious about how the network routing in my ISP affects this. I know DHCP is managed, while PPPoE is dial-up, but used for both DSL and fiber. What should I decide? (I tried both, and it feels a bit confusing... But PPPoE might have been faster, maybe just a placebo.)
Reach out to your internet service provider to get their recommendations? Typically, most fiber connections to homes use DHCP for IP assignment, and occasionally 802.1x is involved.
DHCP offers advantages by maintaining connection without interruption. Key benefits include:
1) Quick and straightforward setup for both endpoints.
2) Clear operation and diagnostic support.
3) Smaller service headers, efficient CPU usage, high performance (experience shows a 2-3x improvement under heavy load).
4) Simple to expand.
Could the switch to a DHCP routed connection from your ISP be responsible for the slowdowns and odd ping issues? It’s possible they might have misconfigured their network or DHCP settings. Maybe it’s not just a placebo effect, though I’m not sure. PPPoE seemed quicker in some situations.
PPPoE serves as an authentication technique. Its use hinges on your ISP's connection verification process. Historically, DSL and VDSL relied on PPPoE for authentication, while DOCSIS used MAC addresses. Both methods operate via DHCP for consumer setups, with no expected performance variation. PPPoE mainly handles connection initiation and user authorization; once connected, the distinction between PPPoE and MAC authentication disappears. TL;DR: Contact your ISP to determine the appropriate settings.
