Hello guys,
I was running some wireshark over my ethernet and I kept finding an ARP broadcast coming from an unknown mac address which is not connected to my router and is asking for IP addresses inside the gateway my router is connected to through PPPoE.
My gateway is 10.0.0.1
I am getting those ARP Broadcasts as well as a DCHP offer made from an IP starting with 100 that doesn't belong to my network.
I traced it and goes back to the ip pool of 10.0.0.1 if I didn't understand it wrong.
I am a bit paranoid. I think this is the ISP sending requests to my router because I replaced the ISP router with my own, and maybe they have setup some VLAN system or something.
But.... I would like to make sure, and if possible block this entirely.
Could you help me?
