Figure 8-10: Network Database screen
The Network Database is an automatically-maintained list of all known PCs and network devices.
PCs and devices become known by the following methods:
• DHCP Client Requests—By default, the DHCP server in this Router is enabled, and will
accept and respond to DHCP client requests from PCs and other network devices. These
requests also generate an entry in the Network Database. Because of this, leaving the DHCP
Server feature (on the LAN screen) enabled is strongly recommended.
• Scanning the Network—The local network is scanned using standard methods such as arp.
This will detect active devices which are not DHCP clients. However, sometimes the name of
the PC or device cannot be accurately determined and will be shown as Unknown.
The Known PCs and Devices table lists all current entries in the Network Database. For each PC
or device, the following data is displayed.
Table 8-1. Known PCs and Devices table
Item Description
Name The name of the PC or device. Sometimes, this can not be determined, and will be
listed as Unknown. In this case, you can edit the entry to add a meaningful name.
IP Address The current IP address. For DHCP clients, where the IP address is allocated by the
DHCP Server in this device, this IP address will not change. Where the IP address is
set on the PC (as a fixed IP address), you may need to update this entry manually if
the IP address on the PC is changed.
MAC Address The MAC address of the PC. The MAC address is a low-level network identifier
which is fixed at manufacture.
Group Each PC or device must be in a single group. The Group column indicates which
group each entry is in. By default, all entries are in the Default group.
