6.2.4 Viewing Current DHCP Address Assignments
When the SL6000/SL6300 functions as a DHCP server for your LAN, it keeps
a record of any addresses it has leased to your computers. To view a table of all
current IP address assignments, just go to the DHCP Server Configuration
page. A page displays similar to that shown in Figure 6.2; the lower half of the
same page shows the existing DHCP address assignments.
The DHCP Server Address Table lists any IP addresses that are currently leased
to LAN devices. For each leased address, the table lists the following
information:
Table 6.3 DHCP Address Assignment
MAC Address
A hardware ID of the device that leases an IP address from the DHCP
server.
Assigned IP Address
The address that has been leased from the pool.
IP Address Expired on
The time when the leased address is to be terminated.

6.3.1 About DNS
Domain Name System (DNS) servers map the user-friendly domain names
that users type into their Web browsers (e.g., “yahoo.com”) to the equivalent
numerical IP addresses that are used for Internet routing.
When a PC user types a domain name into a browser, the PC must first send a
request to a DNS server to obtain the equivalent IP address. The DNS server
will attempt to look up the domain name in its own database, and will
communicate with higher-level DNS servers when the name cannot be found
locally. When the address is found, it is sent back to the requesting PC and is
referenced in IP packets for the remainder of the communication.
