Hi! With the last iproute2 release, ss command output does not differentiate between any-address IPv4 sockets from the IPv6 ones. I don't know if this is an expected behaviour, but the old output looks more useful. Below I pasted the difference between the old behaviour and the new one. I am happy to send a patch if you want. Thanks
