your LAN environment. In addition, you can specify the

Host name

and

Domain (DNS suffix)

of the

HD24613.

3.4.2. DHCP Server

3.4.2.1. Basic

The HD24613 can automatically assign IP addresses to client computers by DHCP. From this
screen, you can specify the

Default gateway

Subnet mask

Primary DNS server

, and

Secondary

DNS server

settings that will be sent to a client at its request. Additionally, you can specify the first

IP address that will be assigned to the clients and the number of IP addresses available for allocation.

Fig. 28. Basic DHCP server settings.

NOTE:

There should be only

one

DHCP server on the LAN; otherwise, DHCP would not work prop-

erly. If there is already a DHCP server on the LAN, disable the DHCP server functionality of the
HD24613.

NOTE:

By default the DHCP server function is disabled.

3.4.2.2. Static DHCP Mappings

IP addresses of servers are often static so that clients could always locate the servers by the static IP
addresses. By

Static DHCP Mappings

, you can ensure that a host will get the same IP address when

it requests one from the DHCP server. Therefore, instead of configuring the IP address of an intranet
server manually, you can configure the server to obtain an IP address by DHCP and it is always as-
signed the same IP address.
