If a laptop is connected both via WiFi and Ethernet to the same network, can the two network cards share the same IP address?
That way, requests for that computer can go to one IP only, and, in case any of the two connections are disconnected, no connection is interrupted.
What I'm imagining is this:
255.255.255.0 subnet, if the WiFi would have IP address
x.x.x.101 and the Ethernet would have IP address
x.x.x.102, someone connecting to the computer via
.101 would be disconnected if the WiFi is interrupted, and someone connecting to the computer via
.102 would be disconnected if the Ethernet cable is unplugged. If both network cards would have the same IP, as long as at least one of them is connected to the network at a time, all connections would stay up.
I have close to no experience with networking. I imagine such a thing would likely exist, but I'm not sure how easy it would be to do it or if it would be worth it.
