why are the ipv6 modules loaded on pure ipv4 setups and if they are always needed why are they seperate modules? net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 ip6_udp_tunnel 16384 1 wireguard udp_tunnel 16384 1 wireguard nf_defrag_ipv6 24576 1 nf_conntrack nf_defrag_ipv4 16384 1 nf_conntrack
