DNS Addresses

The DNS addresses are given by the Internet access provider, except if there is a local DNS

in the home network.

As far as IP addresses are concerned, all the network stations must have the

same network address, e.g., 192.168.0.x or 10.0.x.x, with x between 1 and 254 in

both cases, as illustrated by Figure 10.22.

Configuring NAT and DHCP

The ideal architecture of a PLC home network is the architecture in which the PLC

router is used both as the NAT router and as the DHCP server, with the NAT

enabling the sharing of the Internet connection with all the devices connected to the

network and the DHCP giving all the parameters used by each device for its connec-

tion to the network. These functionalities are available with most PLC

modems-routers intended for the domestic market.

This ideal architecture is illustrated in Figure 10.23.
