A Wide Area Network (WAN) is a network that consists of multiple smaller networks. The most well known WAN is the Internet. To gain access to the Internet, organizations called Internet Service Providers (ISPs) are used. Automatic IP address configuration lets the router receive an IP address from the Dynamic Host Configuration Protocol (DHCP) server of the ISP. DHCP is a network protocol that allows a server to automatically assign an IP address to a connected device. Automatic configuration should only be used if the ISP supports DHCP.
This document explains how to configure Automatic DHCP on a WRVS4400N Wireless Security Router.

Automatic DHCP Configuration
Step 1. Log in to the web configuration utility and choose Setup > WAN. The WAN page opens:
Step 2. Choose Automatic Configuration - DHCP from the Internet Connection Type drop-down list.
Note: Steps 3 to 6 are only necessary if the Internet Service Provider (ISP) requires these fields.
Step 3. Enter the desired the host name that you want to assign to the device in the Host Name field. It is the host name provided by the ISP and is used for identification.
Step 4. Enter the desired the domain name that you would like to assign to the domain in the Domain Name field. It is the domain name provided by the ISP and is used for identification.
Step 5. Choose the type of Maximum Transmission Unit (MTU) from the MTU drop-down list. The MTU specifies the largest packet size that can be transmitted. The types are:
• Auto — The router automatically establishes the MTU for the DHCP.
• Manual — The user establishes the MTU for the DHCP.
Step 6. If MTU manual is chosen, enter the desired MTU size in bytes of the MTU in the Size field.
Note : If you want to configure the DDNS Service, please follow the steps mentioned in the article DDNS Service Settings Configuration on WRV4400N Wireless Router.
Step 7. Click Save to save the changes made in the WAN settings
