Cisco Systems RV016 Dhcp, Dynamic IP used for DHCP Server only, DNS used for DHCP Server only

DHCP	4
Setting Up the DHCP Server or DHCP Relay

NOTE IPv4 only: If you disable both DHCP server and DHCP Relay, configure each device on your network with a static IP address, subnet mask, and DNS settings. Do not assign the same IP address to different computers.

Dynamic IP (used for DHCP Server only)

•Client Lease Time: The Client Lease Time is the amount of time that a network user is allowed to connect to the router with the current dynamic IP address. Enter the amount of time in minutes. Valid values are 5~43,200 minutes. The default is 1440 minutes, which is 24 hours.

NOTE: To receive an IP address from the DHCP server, a client device must be configured to obtain an IP address automatically from a DHCP server. By default, Windows computers are set to obtain an IP automatically.

•Range Start and Range End: Enter a starting IP address and an ending IP address to create a range of IP addresses that can be assigned dynamically. The range can include up to 50 IP addresses, which is the maximum that the server can assign. Valid values are 100~149. Do not include the router’s LAN IP address in this dynamic IP range. For example, if the router uses the default LAN IP address, 192.168.1.1, then the starting value must be 192.168.1.2 or greater.

DNS (used for DHCP Server only)

Optionally, enter the IP address of a DNS Server. You also can enter a secondary DNS server. Specifying a DNS server can provide quicker access than using a DNS server that is dynamically assigned through the WAN settings. You can keep the default setting of 0.0.0.0 to use a dynamically assigned DNS server.

WINS (used for DHCP Server, IPv4 Only)

Optionally, enter the IP address of a WINS Server. Windows Internet Naming Service resolves NetBIOS names to IP addresses. If you do not know the IP address of the WINS server, keep the default, 0.0.0.0.

NOTE To support NetBIOS for DHCP clients, the router uses two methods:

•When the DHCP clients receive dynamic IP addresses from the router, it automatically includes the information of the WINS server to support NetBIOS.

•If a client has a static IP address, then the IP address, subnet mask, default gateway address, and DNS server settings must be configured on the Internet Protocol (TCP/IP) page of the Windows operating system. Then the WINS IP address must be configured on the advanced TCP/IP page. (For more information, refer to Windows Help.)
