lo is a layer 3 (ip) interface. So everything that speaks ip can talk to
it, if you enable routing on the box. So that means in the past I had 32
publically routed addresses in addition to 10.10.10.1 on lo.

# infra.glanzmann.de:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet 10.10.10.1/32 brd 10.10.10.1 scope global lo:0
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

# my laptop at home accessing it via vpn:
(x1) [~] traceroute 10.10.10.1
traceroute to 10.10.10.1 (10.10.10.1), 30 hops max, 60 byte packets
 1  192.168.0.3 (192.168.0.3)  1.594 ms  1.677 ms  1.793 ms
 2  10.10.10.1 (10.10.10.1)  15.613 ms  15.698 ms  17.899 ms

Cheers,
        Thomas
