I'll try to keep it as short as possible.
We've recently removed our proxy server (and gateway) from the network that used to provide Internet access to the entire network on IP address
The new gateway is on address 192.168.0.245. (The people that installed the new gateway - a Mikrotik router - initially used the IP 192.168.0.254 as
well, which needless to say caused chaos on my network.)
Everything is working great again, except whenever I add a new device to the network it automatically picks up 192.168.0.254 as the default gateway.
Meaning I have to manually set the default gateway - which is easy enough, but shouldn't be necessary and is causing problems with "dumb devices".
The old proxy server that was on that address is completely removed from the network.
I've asked the people to check their equipment (router) and make sure there is no traces left of the 192.168.0.254. There is not - according to
The DCHP server has 192.168.0.245 as default gateway.
Pinging the address 192.168.0.254 shows that there is no such device on the network.
I've run several network sniffers, and none of them pick up any trace of a 192.168.0.254 device.
There are no intelligent/managed switches on the network. Only the Mikrotik router which I don't have admin rights for and a WiFi router but I've
checked that as well.
TLDR: Something on my network is broadcasting 192.168.0.254 as the default gateway. How do I find who/what is doing the broadcasting?
