AXIS 231D+/232D+ - System Options
Network - Advanced TCP/IP Settings
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+/232D+. Multiple domains can be separated by semicolons (;). The host name is
always the first part of a Fully Qualified Domain Name, for example, myserver is the host
name in the Fully Qualified Domain Name myserver.mycompany.com where
mycompany.com is the Domain name.
DNS servers - enter
the IP addresses of the primary and secondary DNS servers.
NTP Configuration
The AXIS 231D+/232D+ can obtain the correct time from an NTP server. The address for
the NTP server can either be obtained via the DHCP server, or it can be entered manually.
Host Name Configuration
The AXIS 231D+/232D+ 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.
The e
nable dynamic DNS updates allows you to alias a dynamic IP address to a static host
name, allowing your computer easier access from various locations on the Internet.
Outside users can always access your server using the associated DNS name regardless of
the WAN IP. The DNS server used by the user and/or the DNS server responsible for the
domain in use must support RFC2136 and allow updates from the AXIS 231D+/232D+.
The TTL (Time
To Live) value determines how long (in seconds) the reply from the DNS
server should be remembered when checking that the domain name for the registered IP
address is still valid. For more information, please see the online help .
Link-Local Address
This is enabled by default and assigns the AXIS 231D+/232D+ an additional IP address for
use with UPnP™. The AXIS 231D+/232D+ can have both a Link-Local IP and a
static/DHCP-supplied IP address at the same time - these will not affect each other.
HTTP
The default HTTP port number (80) can be changed to any port within the range
1024-65535. This is useful for simple port mapping, for example.
