minus-squarezurohki@aussie.zonelinkfedilinkEnglisharrow-up3·3 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.

minus-squarepurplemonkeymad@programming.devlinkfedilinkarrow-up3·2 days agoMakes sense, the gateway is never a target of the ip packet, so it’s really only used to find the MAC address of the gateway.
minus-squarezurohki@aussie.zonelinkfedilinkEnglisharrow-up1·2 days agoIt makes sense if you think about it, but seeing IPv6 addresses in the IPv4 routing table still makes professional network engineers stop and boggle for a moment

Thanks I hate it.
