AXIS 231D - System Options
36
Note:
DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may
lead to the situation where the IP address is changed and you lose contact. Configure the options for noti-
fication of IP address change (see Services below) to receive notification from the Network Dome Camera,
when the IP address has been changed.
Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 231D by host name
which is always the same, regardless of the IP address.
• Auto-Configure Link-Local Address is enabled by default and assigns the
AXIS 231D with an additional IP address for the UPnP protocol. The AXIS
231D can have both a Link-Local IP and a static/DHCP IP address at the same
time - these will not affect each other. See Network - UPnP, on page 37.
DNS Configuration - DNS (Domain Name Service) provides the translation of host names
to IP addresses on your network.
Obtain DNS server address via DHCP - automatically use the DNS server settings provided
by the DHCP server. Click the View button to see the current settings.
Use the following DNS server address - enter the desired DNS server by specifying the
following:
• Domain name - enter the domain(s) to search for the host name used by the
AXIS 231D. Multiple domains can be separated by semicolons (;). The host
name is always the first part of a Fully Qualified Domain Name, e.g. myser-
ver is the host name in the Fully Qualified Domain Name myserver.mycom-
pany.com where mycompany.com is the Domain name.
• Primary DNS server - enter the IP address of the primary DNS server.
• Secondary DNS server - will be used if the primary DNS server is unavail-
able.
Host Name Configuration - The AXIS 231D can be accessed using a host name, instead of
an IP address. The host name is usually the same as the assigned DNS Name. It is always
the first part of a Fully Qualified Domain Name and is always one word, with no period.
For example, myserver is the host name in the Fully Qualified Domain Name
myserver.mycompany.com.
