PINGing your IP Address
By sending a packet to the specified address and waiting for a reply, the PING (Packet Internet
Groper) can determine whether a specific IP address is accessible; it also provides a particularly useful
method for confirming addressing conflicts with your Network IP Camera on the network.
Having disconnected your Network IP Camera, follow the instructions below in association with
Symptoms, Possible Cause and Remedial Actions, on next page, and run the PING utility to
troubleshoot TCP/IP problems on your network.
1. Start a DOS window
2. Type ping x.x.x.x, where is the IP address of Network IP Camera
3. The subsequent replies will provide an explanation as to the case as to the cause of the problem.
