I split my network(s) into subnets (sharing the same wire, not to be confused with the actual subnets which don't share the same wire) which correspond to routability policies. This in turn involves firewall rules, routing table entries, and DHCP configs corresponding to those subnets.
I give away the software which does the following. I get this (and a lot more) for every host on my network, and I know what every host is.
