DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual 
clients to obtain TCP/IP configuration at start-up from a server. You can configure the 
NBG420N’s LAN as a DHCP server or disable it. When configured as a server, the NBG420N 
provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have 
another DHCP server on that network, or else the computer must be manually configured.
Click the DHCP Table (Details...) hyperlink in the Status screen. Read-only information here 
relates to your DHCP status. The DHCP table shows current DHCP client information 
(including IP Address, Host Name and MAC Address) of all network clients using the 
NBG420N’s DHCP server.
