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 233D.
Multiple domains can be separated by semicolons (;). The host name is always the first part
of a Fully Qualified Domain Name, e.g. 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
Obtain NTP server address via DHCP - check this radio button to automatically look up
and use the NTP server settings as provided by DHCP. Click the View button to see the
current settings.
Use the following NTP server address - to make manual settings, check this radio button
and enter the host name or IP address of the NTP server.
Host Name Configuration
The AXIS 233D 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 enable dynamic DNS updates allows you to alias a dynamic IP address to a static host
name, allowing your computer to be more easily accessed 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
233D.
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
