Why would 2 Network IP cameras require 2 different DNS addresses for the Primary DNS
Posted on 2010-09-14
I have a Panasonic C-131A and D-Link DCS-920 camera. I talked to there tech support and Panasonic had me set the Primary DNS to my default gateway 192.168.0.1 and the secondary dns to 4.2.2. D-Link had me set the Primary DNS to 67.xx.72.xxx and the secondary DNS to 67.xx.77.xxx. These are both Comcast DNS servers I assume since my provider is Comcast.
After some minor issues and some help from Ken (Experts Exchange) I can now access both the cameras from outside and inside my network ! However I would be curious about:
1. Why my panasonic c131 uses my default gateway as the primary dns and 4.2.2 as the secondary server.
2. Why D-Link requires to use the 67.xxx as my primary and secondary
2. How do I ping my dyndns (For D-Link I subscribed to DynDNS to obtain a URL for my camera) and do i need to do this from outside my network
