Assigning IP Addresses
In the Hotwire DSLAM network model, there are two distinct domains:
H a management domain
H a service domain
Within the management domain, there are two subnets as described in
Management Domain Components
in Chapter 4,
Components of the Network
Model
. Within the service domain, one of two IP address allocation schemes can
be followed: host addressing or structured subnet addressing. The following
sections describe these schemes.
