DHCP can provide a station with a certain range of addresses and that each of these
addresses is negotiated and is valid only for a given period of time.
DHCP Architecture
The DHCP is based on a client-server architecture. In the case of PLC networks, the
DHCP client is the device connected to the PLC network and the DHCP server is the
PLC modem-router.
In the example illustrated in Figure 10.25, there is only one DHCP server
located at the InternetBox level for recent IAP offers or at the Internet modem level,
but a network can be made up of several gateways for access to the Internet and
therefore of several DHCP servers. Using several DHCP servers does not trigger any
network constraints.
When a station initiates the DHCP protocol, this protocol provides it with the
following parameters:
•
IP address;
•
Subnet mask;
•
Default gateway;
•
DNS address;
•
Domain name.
