[c-nsp] Large networks

[Randy McAnally]

In a dedicated server hosting environment, each customer should have their own
VLAN and subnet.  True, it may waste a few IPs, but keep in mind when the
customer expands to two or more servers, they can utilize additional IPs from
their existing VLAN even when the servers are not physically close to each
other.  It makes customers happy, and it makes sysadmins sleep easier.
