All good to me ! Thanks for the quick fix

Could you also add the tests for IPv6 ?
The routes were also provided in the results I posted previously

It is the same output as the currently mocked read_routes6() for 10.9.5

I was working on the same project on ubuntu for a while and then got back here on Catalina to update scapy. Worked like a charm. Thanks for the fix!
