Dhcp Server Parameters; Figure 13-31: Dhcp Server Summary - AudioCodes MP-202 User Manual

Your gateway's DHCP server:
Displays a list of all DHCP host devices connected to the gateway
Defines the range of IP addresses that can be allocated in the LAN
Defines the length of time for which dynamic IP addresses are allocated
Provides the above configurations for each LAN device and can be configured and
enabled/disabled separately for each LAN device
Can assign a static lease to a LAN PC so that it receives the same IP address each
time it connects to the network, even if this IP address is within the range of addresses
that the DHCP server may assign to other computers
Provides the DNS server with the host name and IP address of each PC that is
connected to the LAN
Additionally, the gateway can act as a DHCP relay, escalating DHCP responsibilities to a
WAN DHCP server. In this case, the gateway will act merely as a router, while its LAN
hosts will receive their IP addresses from a DHCP server on the WAN.
With the gateway's optional Zero Configuration Technology feature, the IP Auto Detection
method detects statically-defined IP addresses in addition to the gateway's DHCP clients. It
learns all the IP addresses on the LAN, and integrates the collected information with the
database of the DHCP server. This allows the DHCP server to issue valid leases, thus
avoiding conflicting IP addresses used by other computers in the network.

Figure 13-31: DHCP Server Summary

If In the column 'Service' of the 'IP Address Distribution' screen, if a gateway
is indicated 'Disabled', then DHCP services are not being provided to hosts
connected to the network through that gateway. This means that the gateway
will not assign IP addresses to these computers, which is useful if you wish to
work with static IP addresses only.
