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
210A/211A. 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.
Note: This is not mandatory with regard to secondary DNS servers.

NTP server can either be obtained via the DHCP server, or it can be entered manually.

Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 210A/211A an additional IP address for
use with UPnP
™
. The AXIS 210A/211A 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 security port mapping.
HTTPS
The default HTTPS port number (443) can be changed to any port within the range
1024-65535. HTTPS is used to provide encrypted web browsing.
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” i.e. the Internet. Security on the private network (LAN) is increased since most
broadband routers are pre-configured to stop any attempt to access the private network
(LAN) from the public network/Internet.
