Network Management

Instead of providing a list of IP addresses, most larger providers simply have subnet blocks attached to networks. For example:

vlan224: 192.168.24.0/24
vlan228: 192.168.28.0/24
vlan316: 172.16.16.0/24

Using these subnet definitions instead of a list of individual hosts can make larger deployments much easier. Accounting should still be done on a per-IP basis, but those entries can be written on demand to an accounting file, and absence of an entry would mean the IP address is available.
