Is it possible for someone to send an IP broadcast packet over all internet? I know that routers do not allow that, but is there any other way?

  • Imagine if someone could do this. Then I could just send broadcasts all day and overload everyone's internet connection. The internet wouldn't work. Does the internet work? Yes (mostly). Therefore I can't do this. – user253751 Apr 1 at 10:43

Broadcasts (IP=255.255.255.255) are not forwarded by routers. Devices that do are called bridges or switches, not routers.

Directed broadcasts (IP=192.0.2.255/24) could be forwarded to a specific network, if the router was specifically configured to do so. But routers on the Internet are never configured that way.

No.

Broadcasts and multicasts are dropped all over the Internet.
