DNS Domain Name Services
Normally the camera doesn't use DNS services, such as resolving computer names, such as www.edgertronic.com, into an IP address. There is at least one case when DNS may be used, namely when resolving the name of the NTP Network Time Protocol server into an IP address. Since the majority of the camera code is normal Linux applications, it should not be a surprise that the camera supports the normal resolv.conf configuration file used by DNS services.
Updating resolv.conf configuration file
You can replace the factory default resolv.conf configuration file by storing the file on the SD card or a USB storage device and powering on the camera.
A typical resolv.conf file looks like:
nameserver 184.108.40.206 nameserver 220.127.116.11
To verify the file was properly installed, browse to http://10.11.12.13/static/etc/resolv.conf
replacing 10.11.12.13 with your camera's IP address as necessary.
