I am connected to the internet through a proxy. When I went to What Is My IP, it shows a different address than that of my proxy. It's is showing the same IP address even when I connect through a different machine in the same LAN.
So can I conclude that I am using overloading NAT because the same IP address is assigned to all the machines in the LAN and that IP address is not the IP of the proxy server?
If so, overloading NAT uniquely identifies your machine with a port number(since the IP address is the same for all machines). But I am not able to see the port number in.
How to see my machine's port number?
Note:
What Is My IP shows my IP(nat or whatever) and also the proxy server's IP in the Possible proxy Detected
section
I believe the translation information doesn't go beyond the router. Why do you need to know the port number? – Sathyajith Bhat – 2012-04-30T06:56:07.847
@Sathya : I need to know the port number to be sure that the nat is actually mapping my ip to a public ip. As I said I also have a proxy server with a private address(not a public ip). So I have a doubt that the nat is providing a public ip to the proxy server and not to my machine. Can such a thing happen? – Ashwin – 2012-04-30T06:59:50.363
On large networks that's what (generally) happens. All computers talk to a caching proxy server which then connects to the Internet. – Sathyajith Bhat – 2012-04-30T07:04:26.213
This question is unclear. The reasons for asking this question are unclear. Are you asking about NAT principles, Proxy principles, privacy of internal IP-address, function of traceroute or something else. Voting to close. Please clarify question. – RedGrittyBrick – 2012-04-30T09:55:16.577
