standard dial-up. Cable Internet and DSL are examples of broadband.
DHCP Server
DHCP (Dynamic Host Configuration Protocol) server is a server running the
DHCP protocol to automatically assign IP addresses to client stations on a TCP/
IP network. Using DHCP eliminates the need to manually assign IP addresses
to each device on your IP8100 series telephone.
DHCP Client
The DHCP client is a device that obtained a DHCP lease from a DHCP server.
DMZ
DMZ (Demilitarized Zone) is a part of a network that is located between a secure
LAN and an insecure WAN. DMZs provide a way for some clients to have
unrestricted access to the Internet.
DNS
DNS stands for Domain Name System. DNS converts domain names to the IP
addresses that all machines on the Internet have. It translates from name to
address and from address to name.
Domain Name
The domain name is the readable version of an Internet site address. A
typical domain name has the form www.somedomainname.com or www.
somedomainname. org, etc.
Filter
Filters define how specific data is transmitted or received from the LAN port to
the WAN port. For example, the IP8100 series telephone can filter specific LAN
IP addresses from accessing certain services on the Internet.
Firewall
Firewalls are used to keep networks secure by preventing unauthorized Internet
users from accessing services on your local network. The firewall on the IP8100
series telephone can be configured to allow Internet users to access certain
services on your LAN using Virtual Servers and the DMZ Host.
