micropython libraries for ethernet w5500 shield - libraries

Question

I am trying to build a project using rpi pico and W5500 shield module with micro python.
I am struggling to find the proper libraries for that but I am unsuccessful so far. The documentation of micro python references in https://docs.micropython.org/en/latest/library/network.LAN.html?highlight=lan%20module:
class LAN – control an Ethernet module¶
This class allows you to control the Ethernet interface. The PHY hardware type is board-specific.
Example usage:
import network
nic = network.LAN(0)
print(nic.ifconfig())
# now use socket as usual
...
but I am not sure which network library to look for or how to install it in thonny and so the importing is unsuccessful. When in Thonny tools/manage packages/ and I search on PyPl for "network" there are many libraries coming up but which is the proper one?
Can somebody point out the proper library?

You'll need a MicroPython firmware build that includes support for the Wiznet modules with RP2040 / Pico. There's a guide on the Wiznet GitHub (it also goes on to talk about how to compile it yourself, if you need to go that far). It does look like the support for the W5500 on rp2040 has only just hit the nightly builds of MicroPython (I usually run with the current nightly versions myself, so you could give the latest build direct from micropython.org a try)
Once you have a firmware that includes the right support, the following code should work:
import network
nic = network.WIZNET5K()
nic.active(True)
# to print IP address etc
nic.ifconfig()
Also, the current link to the MicroPython docs on these network adapters is this one, rather than the link you shared to the generic network / LAN class.
