Interfacing W6100 (MKR-)Ethernet Shield with Arduino MKR Zero

Hi everyone,
I’m facing difficulties in establishing IPv4 connectivity between a W6100 (MKR-)Ethernet Shield and an Arduino MKR Zero Board. Despite using the Wiznet Ethernet.h (Ethernet-IPv6) library for the W6100 shield, I’m unable to successfully ping the shield from the MKR Zero board. The Ethernet-IPv6 library works fine with the ChatServer example (with IPv6), but I specifically need IPv4 functionality. How can I configure the hardware and software to enable successful IPv4 communication between the MKR Zero board and the W6100 Ethernet shield using SPI?
Please guide.
