I see, I thought routers knew not to do dhcp on the Wan port
Typically they do. Which is great until you get a student who doesn’t understand WAN vs LAN and plugs both connections into the LAN ports. Never underestimate the power of a Stupid User.
They do know enough to not send DHCP leases upstream..
If you plug the dorm ethernet jack into the LAN side of a consumer router, there's a chance they don't.
Sure, you can catch this if you watch the dhcp leases your router is handing out, but..
I'm assuming OP is at least smart enough to know that the port that's on its own/a different color/somehow different from the others is the one that goes into the wall. It sounds like they have at least that level of competence.
I’m sure OP is given the more technical nature of Lemmy users. But this thread is about the average college student with no networking knowledge.
ETA: Sorry that I specified you weren’t talking about the same thing the rest of us were in this thread.
Which is all well and good until you get someone who plugs both connections into the LAN ports.
Downvoting just because I pointed out a scenario you didn’t think of isn’t so classy.
No. I'm downvoting because your first comments stated it will happen if the router is set up to offer leases. Not that it could happen if a user ignores the quick start guide that says "plug this port into the wall." Then got all pissy with that other guy who pointed out that your article was about DHCP servers, not routers.
I’m not getting pissy about anything. That’s projection on your part, reading a tone that wasn’t there. Just because you’re in a bad mood today doesn’t mean the rest of the internet is.
