Unknown Netgear IP address on network (CG3000V2)
Recently got a new cable modem from Optus (CG3000V2) and enjoy using Netgear Geni, but confused by an unknown device that keeps appearing at the same IP address (192.168.0.5). Recently checked Norton...
Use ping from the windows command prompt to ping the ip address, if it does not respond, it may not exist - most devices will respond to a ping request, unless there is a firewall blocking the request.
I don't need the MAC, there's no definitive way to determine the device from it, and not being a user of either Netgear Genie or Norton Network Map, I can't tell you how either one works - experience with Microsoft's LLDP (link layer discovery protocol) network mapping, which is what I suspect is being used by Genie & Norton, has shown me that the technology is perhaps not mature enough to be considered reliable - I have yet to see it show an accurate map (a quick check this morning shows one of my three switches and a printer missing, and a server showing up twice).
Many routers are also not reliable in their presentation of attached or connected devices - there are two methods generally used to gather the information, both with their quirks, and I have no idea which one the CG3000 uses.
If this sounds like I have little faith in these technologies, it's because I don't - I've investigated the quirks, I know why they don't work, I don't know of a guaranteed reliable way, and I just don't loose sleep over them.
If I want to know what is on my network (usually so I can find where it is, I will either use FING (which runs on an Android device) for a quick & easy check, or PacketTrap's network tools.
