Mhh, ifconfig is obsolete on Linux and has been replaced by ip. The IPv4 and IPv6 neighbors can also be displayed with ip neighbor and ip -6 neighbor respectively. For the routing table, the classic way is to use ip route or ip -6 route. netplan has only limited capabilities if you want to configure an interface specifically – furthermore, in my experience it is also more of an Ubuntu thing. On user computers, NetworkManager is often used instead.
