On this article the user can configure the internal network settings of the D-Link DIR-645 router and also able to configure the built-in DHCP server to assign IP addresses to computers on the network. The IP address that is configured here is the IP address that is used to access the Web-based management interface. If you change the IP address in this section, you may need to adjust your PC’s network settings to access the network again.

Router IP Address:

Enter the IP address of the router. The default IP address is 192.168.0.1. If you change the IP address, once you click Apply, you will need to enter the new IP address in your browser to get back into the configuration utility.

Default Subnet Mask:

Enter the Subnet Mask. The default subnet mask is 255.255.255.0.

Host Name:

Enter a Host Name to identify this device.

Local Domain Name:

Enter the local domain name used here. (Optional).

Enable DNS Relay:

Uncheck the box to transfer the DNS server information from your ISP to your computers. If checked, your computers will use the router for a DNS server.

D-Link DIR-645 DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. This device has a built-in DHCP server. The DHCP Server will automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the router. The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.

Enable DHCP Server:

Check this box to enable the DHCP server on your router. Uncheck to disable this function.

DHCP IP Address Range:

Enter the starting and ending IP addresses for the DHCP server’s IP assignment.

DHCP Lease Time:

The length of time for the IP address lease. Enter the Lease time in minutes.

Always Broadcast:

If all the computers on the LAN successfully obtain their IP addresses from the router’s DHCP server as expected, this option can remain disabled. However, if one of the computers on the LAN fails to obtain an IP address from the router’s
DHCP server, it may have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets. Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at the cost of increased broadcast traffic on the LAN.

NetBIOS announcement:

Check this box to allow the DHCP Server to offer NetBIOS configuration settings to the LAN hosts. NetBIOS allow LAN hosts to discover all other computers within the network, e.g. within Network Neighborhood.

Learn NetBIOS from WAN:

If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn
this setting off to configure manually.

NetBIOS Scope:

This is an advanced setting and is normally left blank. This allows the configuration of a NetBIOS ‘domain’ name under which network hosts operate. This setting has no effect if the ‘Learn NetBIOS information from WAN’ is activated.

DIR-645-Network-Settings-3

NetBIOS node type:

This field indicates how network hosts are to perform NetBIOS name registration and discovery. H-Node, this indicates a Hybrid-State of operation. First WINS servers are tried, if any, followed by local network broadcast. This is generally the preferred mode if you have configured WINS servers. M-Node (default), this indicates a Mixed-Mode of operation. First Broadcast operation is performed to register hosts and discover other hosts, if broadcast operation fails, WINS servers are tried, if any. This mode favours broadcast operation which may be preferred if WINS servers are reachable by a slow network link and the majority of network services such as servers and printers are local to the LAN. P-Node, this indicates to use WINS servers ONLY. This setting is useful to force all NetBIOS operation to the configured WINS servers. You must have configured at least the primary WINS server IP to point to a working WINS server. B-Node, this indicates to use local network broadcast ONLY. This setting is useful where there are no WINS servers available, however, it is preferred you try M-Node operation first. This setting has no effect if the ‘Learn NetBIOS information from WAN’ is activated.

Primary WINS Server IP address:

Configure the IP address of the preferred WINS server. WINS Servers store information regarding network hosts, allowing
hosts to ‘register’ themselves as well as discover other available hosts, e.g. for use in Network Neighborhood. This setting has no effect if the ‘Learn NetBIOS information from WAN’ is activated.

Secondary WINS Server IP address:

Configure the IP address of the backup WINS server, if any. This setting has no effect if the ‘Learn NetBIOS information from WAN’ is activated.
