pingalive for Ethernet W5500

[JefersonDeLeon]

Is this compatible with W5500 connected to esp8266?

It is using lwIP, so it is generic but will work only if you use the esp8266's w5500 driver for lwIP.

Is it possible to ping specific IP?

Im trying to implement this ttps://github.com/NicksonYap/Arduino-Ping-W5500 to check if the esp is connected to server ip via lan but i dont want to use ethernet2 library.

Yes, any IP even IPv6 but you must be using lwIP.
This repo will not work with Ethernet1 nor Ethernet2.
