Basic Networking Concepts - Matrox Iris E Series Installation And Technical Reference

B a s i c n e t w o r k i n g c o n c e p t s
The Matrox Iris E-Series user guide uses the following concepts to help walk you
through the process of configuring your Matrox Iris E-Series to communicate with
your computer.
• DHCP. Dynamic host configuration protocol. DHCP is a protocol that requires
a client and a server. Your computer and Matrox Iris E-Series are DHCP clients.
A DHCP server can find DHCP clients on a network and automatically assign
them each a unique dynamic IP address. DHCP also associates a computer's name
with its IP address so that, to connect to the computer, you can use its name instead
of its IP address. This domain name service (DNS) is also provided by NetBios.
Note that if a DHCP server is not available, the Auto IP service of a DHCP
❖
client can assign your computer a unique dynamic IP address within a given
subnet.
• DNS. The domain name service provides the association between a given IP
address and the name of the computer using that IP address. The association
between an IP address and a computer's name is stored in a DNS resolver cache,
located on the computer that requested the association. Without a DHCP server,
if the IP address of a computer changes, the DNS cache on all the computers using
the computer's name must be cleared to re-establish the association. Note that
with a DHCP server, DNS is managed by the server and not by the client.
• Dynamic IP address. A dynamic IP address is an IP address that can change. If
not using a DHCP server, the Auto IP service of a DHCP client assigns a dynamic
IP address that, by default, might change each time your computer (and/or your
Matrox Iris E-Series) reboots. A DHCP server, if used, can assign an IP address
to a computer for a fixed amount of time. When that time expires, the DHCP
server can assign a new IP address to that computer.
• LAN. Local area network, also called a network. A LAN is a group of computers
connected to communicate and share resources and data. In this manual, a LAN
has several computers (servers) that are dedicated to serving the others (clients) in
a client/server architecture.
