minus-squarezurohki@aussie.zonelinkfedilinkEnglisharrow-up3·8 days agoIf you use a /23 you can use the middle .0 too. My favourite dumb networking trick though is that Linux lets you use an IPv6 address as an IPv4 gateway. ip -4 route add default via inet6 fe80::1 dev eth0 That works so long as the gateway is running dual stack.
