I found this article: https://www.raspberrypi.com/news/how-to-add-ethernet-to-raspberry-pi-pico/ If you follow it, your Pico will obtain an IP address from the router (or other DCHP server) using DHCP. Therefore, for example, if you set your router's DHCP server to assign addresses for 172.16.0.0 with a mask of 255.255.0.0 (or 172.16.0.0/16), it would be able to hand out up to 65534 IPv4 addresses (not including the router itself) in the range of 172.16.0.1 to 172.16.255.254 If you need the Pico to have a fixed IP address, most DHCP servers can be set to assign specific IP addresses based on the device's MAC address. I haven't looked further but it's also very likely that you can configure the ethernet port of the Pico itself to have a static IP address and a mask of any length. -- Scott
