AXIS P8221 - System Options
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 device. Multiple domains can be sepa-
rated 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.
Note: This is not mandatory with regard to 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 create manual settings, check this radio button and enter the host name or IP
address of the NTP server.
Host Name Configuration
AXIS P8221 can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned
DNS Name.
Link-Local IPv4 Address
This is enabled by default and assigns the device an additional IP address for use with UPnP
TM
. The device 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 and HTTPS
The default HTTP/HTTPS port numbers (80 and 443 respectively) can be changed to any port within the range 1024-65535.
This is useful for simple security port mapping, for example.
NAT traversal (port mapping) for IPv4
A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by
forwarding network traffic from the private network to the “outside”, that is, the Internet. Security on the private network
(LAN) is increased since most broadband routers are pre-configured to stop attempts to access the private network (LAN) from
the public network (Internet).
Use NAT traversal when your device is located on an intranet (LAN) and you wish to make it available from the other (WAN)
side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router is
forwarded to the device.
