Chapter 5 The LAN Configuration Screens

MAX-207HW2R User’s Guide

Subnet Masks

Subnet masks determine the maximum number of possible hosts on a network. 
You can also use subnet masks to divide one network into multiple sub-networks.

DNS

DNS (Domain Name System) is for mapping a domain name to its corresponding 
IP address and vice versa. The DNS server is extremely important because 
without it, you must know the IP address of a networking device before you can 
access it.

DHCP

A DHCP (Dynamic Host Configuration Protocol) server can assign your MAX-
207HW2R an IP address, subnet mask, DNS and other routing information when 
it’s turned on.

5.2  DHCP Setup

Click ADVANCED > LAN Configuration > DHCP Setup to enable, disable, and 
configure the DHCP server in the MAX-207HW2R.
