This is only showing the IP 10.0.0.1/27 which is a single IP on the box.
You dont get a range of IP's by using a specific mask on the interface.

You have 10.0.0.2 bound to a system somewhere which is nice but has
nothing to do with lo:1

Because you are doing it wrong.

You need to actually have the IP bound to an interface on the server for
it to work.
