Automatic IP. Auto IP is a client-side service that assigns a dynamic IP address
that, by default, might change each time your computer (and/or your Matrox
Iris GT) reboots. Auto IP is used when your Matrox Iris GT is configured to get
its IP address automatically from a DHCP server, and either there is no DHCP
server present or the DHCP server is not responding. Auto IP is a service of a
DHCP client.
Dynamic host configuration protocol. DHCP is a protocol that requires a client
and a server. Your computer and Matrox Iris GT are DHCP clients. A DHCP
server serves DHCP client requests on a network and automatically assigns each
DHCP client a unique dynamic IP address. DHCP works with a DNS server to
associate 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. Netbios over TCP/IP (an older
client-side technology) can provide the name association whenever a DNS server
is not present on a LAN.
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.
Domain name service. DNS 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 a DNS server and not by the client.
