routers will usually feature DHCP out of the box, so if the ethernet connectivity is functional end to end, and the router is selected by configuring the desktop to do so, the desktop’s ARP (ethernet-IP) table entries will be thereafter loaded by the router using the ARP protocol. Or something like that.
AI Overview
Netgear Ethernet switches are inherently transparent bridges operating at Layer 2, requiring no special “bridge mode” configuration to connect devices. If you are using a Netgear router or modem/router combo and want to use it as a bridge, you must enable Bridge Mode or AP mode in settings to disable NAT and DHCP, effectively turning it into a switch/access point.
