How to change the ip address for a domain from the java program itself?

Question

we manually do the host entries to redirect a URL to a particular IP, Is there any way to do that in the automation script itself(in JAVA)? So it points to a particular IP without every time changing the host entries manually from the system hosts file.

You can use BrowserMob-Proxy to fake IP addresses on the fly. You need to add your custom domain resolver like shown here:

browserMobProxy.setHostNameResolver(new NativeResolver(){
    @Override
    public Collection<InetAddress> resolve(String originalHost) {
        if("webelement.click".equals(originalHost)){
            try {
                return Arrays
                        .asList(
                                new InetAddress[]{
                                        InetAddress.getByName("127.0.0.1")
                                });
            } catch (UnknownHostException e) {
                e.printStackTrace();
            }
        }
        return super.resolve(originalHost);
    }
});

In this example you override the IP for one particular domain name. In this post you can find more insight on the issue.
