Re: what is ip spoffing why we use? plzz tell me in detail

Quite late that I see this email but surprise why it was left unanswered.

Sometimes, your application works based on client IP. For example a public survey will require unique IP - it will deny multiple requests from single client IP. How would you test such an application?

IP Spoofing (as explained in VUGen book) caters such situations. It sends requests to application from various IPs (of local IP range) and LoadRunner takes care to ensure which request successfully had a corresponding response.

In addation to ' Kamran Khan ' point. Performance testing should be realistic. Users are accessing the application from different IP's. We need to simulate this, for this we are doing the IP Spoofing.

Some times loadbalacers uses the IP to distribute the load between several cluster's nodes. In this scenario, if all the simulated users uses the same IP probably all the request will go against the same node. To avoid that you can assign each user a different IP and the load balancer will distribute the load more efficiently (and will be more realistic).

I don't see much value in IP spoofing compared to tools like Shunra and all. IP spoofing is ideal for functional testing. Not much value for load testing.  If your application functionality had been designed to work only with unique IP addresses, it will be required. But once it resolves the server host for the first DNS resolution, all the IPs in that particular LG will still fetch the resolved address from the DNS cache.
