Why Does Wireshark Give Wrong IP Address?

edit

You're suggesting it has two IP addresses - one for each interface.

While I am too ignorant to debate that with you I can tell you that I've used this method quite often before with Dahua cameras and with Foscam cameras - and I got the method from a person (on the web) who apparently used it for good effect.

It's been my thought that it works because these devices have a static IP. When we buy them we have to configure them with an IP of our choice and replace its current IP - usually because its current IP is out of our own range.

I also think - I'll check this today - that I can't find them on the wifi adapter because of range problems. Typically I've got cameras in the 10.x.x.x range and our Lan uses the 192.x.x.x range ...(more)

If your PC has both an Ethernet and WiFi interface, you can plug your Ethernet cable into your router and keep your WiFi interface enabled. Run ipconfig /all from a command prompt and you will see that both interfaces have a unique IP address assigned to them. One interface will be preferred based on metrics and it's typically the Ethernet interface that is preferred. You can check the routing table by running route print; the lower metric is the preferred interface. Anyway, this is just to demonstrate to you that interfaces do indeed have their own IP addresses, even when connected to the same LAN.

Now, if you connect the camera directly to your computer, it should be possible to communicate with it in theory, but the camera would have to support connections over that interface - perhaps ...(more)

What I am trying to do is find the IP address of cameras that I can no longer connect with. Cannot 'find'.

There's different reasons why things get like that. Just take it that I've got Foscam and Dahua cameras that I don't know the IP of.

I do what you're suggesting. That's the whole thing. I take an IP wifi camera and instead of using the wifi - where it can't be 'found' - I ethernet connect it to my computer. To the ethernet adapter. And I give that adapter an IP address in the range that I think the camera is probably at. Usually 10.x.x.x Then I 'look' for it with wireshark.

The first part of that is the normal procedure for setting up a new Foscam or perhaps any other wifi IP ...(more)
