I am working on the User login record. Here i have to record the Destination Machine Name, Destination IP address, Source Machine Name and Source IP address. I faced two problems while handling with Servlets.
To obtain the Source Machine Name and Source IP address, we used httpServletRequestObject.getRemoteHost() and httpServletRequestObject.getRemoteAddr(). It is giving me, the same IP address, ie, 127.0.0.1. Is there is any way, how to obtain the Destination Machine Name and Destination IP address.
In our project, we are using proxy server. So whenever client is trying to communicate our application, its request comes through us via proxy server.
Is there is any way to get the client machine ip address and its machine name?

When IPv6 is widespread, the need for NAT will decrease. And perhaps the use of NAT will decrease as well. Expect this to happen before the Sun burns out.
Well, although I'm agreeing with you, I just wanted to point out that NAT is used for more than just to reduce the number of public IPs required by any particular site. It is primarily used to hide the NAT'd machines from the outside network - as a security measure.
