I tried to use commview v5 , I disbaled wired card and I used wireless card, i found this ip address as Local 169.254.242.9 (windows default) and this ip address as Remote: 38.101.111.18

1- Why this ip address 169.254.242.9 ( assigned by windows to diconnected nic ) communicated with the 38.101.111.18 ?


2- Why there are two colors under "Packet" Tab,,,blue and purple ?

I'm not familiar with this product but the 169.254.x.x I.P address is an address XP assign your network card if it is unable to find a DHCP server to get an address. click me !

Also, maybe one of your other threads yields the answer :wink:

This is not what i am looking for, I am aware of this ip address why it has been assigned to the disconnected NIC. But my query why does this disconnected ip address communicate with real public ip address ????(Can you imagine that diconnected ip address talk to live ip address??), therefore all my threads that you have posted did not answer my question, therefore I posted my thread here

Are you sure ther is actually any traffic going betwee the interfaces ?

What does your routing table look like ? (ROUTE PRINT)
Take a look at active connections (NETSTAT -a)

You meant : "Are you sure there is not actually any traffic,,,,,,,,,,,,did not you ? If this the case, a cable unplugged from the NIC, then I can say definitely I am sure that there is no traffic.

Hi,

Your routing table shows no routes to the 38.101.111.x network so you will not be directly communicating with this address.

Also, I made a typo NETSTAT -N will show you addresses and port number that you are communicating with.

Now my concern is :

wired card that I have got in unplugged form cable,,,ok ?

This wired card (unplugged form cable) has been assigned default ip address form windows,,,,do you agree ?

Can unplugged NIC card (athough it has been assigned ip address ) communicate with public ip address ( I do not care if it is direct communication or indirect communication) ?

Note: When I repeated the experiment , I did not use the same web page that I had accessed before, therefore as a result you we are not going to see the same output from "route -print" command


I hope you get what is my concern.

Thanks

If your card is unplugged then it cannot communicate at all ....

For this reason I raised my thread, why CommView shows me this communication ?!!

Reply to zillah

Hmmmmm ....

I don't know the Commwin product but if a card is unplugged then no traffic can flow. I wouldn't be worried over this.

This is what the logical should be.

I would not either, but CommView showed me the communication with public IP this confused me

Try using PERFMON to monitor the network interface for any traffic to satisfy yourself it is "dead"

Use the 'Network Interface' performance object .....
