RE: Am I over reacting?

I wouldn't worry too much about it, for these reasons:

1) IP addresses have to be revealed all the time in order for network
communications to work.  DNS servers hand them out all the time.  Having
them displayed on the screen isn't much of a giveaway - they can be seen
in arp tables, using sniffers, and plenty of other tools.

2) There is a better than even chance that the IP address you are seeing
is not the actual address of the computer being used.  Most corporate
AND home customers these days are using RFC1918 addressing and using
Network Address Translation to make use of a smaller number of available
IP addresses.

Subject: Am I over reacting?

I'm not sure if I'm over reacting on this or not since
I'm new to the security scene.  This morning during an
on-line seminar that one of our customers was holding;
the presenter had his desktop shared out (so you could
see everything).  One thing I noticed about the web
meeting software was that it was showing everybody's
IP. I've used other web meeting companies and none of
them showed the IP's.  From my understanding if you
have the IP your halfway to getting into their system.
 If I was a bad boy I could run a port scan to see
what they where running and then exploit it. Is my
thinking correct or am I off base and over reacting?
 
Thank you for your input,
 
Michael Horn
