The other oddity is why does having the /24 statically routed along with the /18 cause any IP on the internet to be added to the ARP cache? That part right there is what is most confusing to myself.

Agreed, that doesn't seem to make any sense!

I figured it out. Proxy ARP is _very_ touchy when it comes to subnets. Since the netmask is a /32 subnet on the host vif the route works if added as on the guest (versus a /24). This allows RedHat to do what they want and I need not worry if a user turns of zeroconf support on their own now.
