Can anyone tell me, how I can get in java the packet of IP and then modify it? Maybe there is a special library, which could help me?

Thank you in advance.

Thank you for your answer, but it's not what I'm looking for. I want to know, how to get to the lower-layer, because I want to change the IP header . I have to write some data in IP.I search the forum, but I couldn't find the answer for this question. I will be really grateful for help.

Thank you in advance.
