Even if you do so it will not work. When the packet will reach next hope it will be dropped because of bad CRC.

Not possible. the IP headers are set on OS level. You have to modify the raw packet in that case, which isn't even possible on Windows. You would have to do that in Linux. Are you sure that you don't just want to use a proxy?

Is it possible, yes - take a look at RawIP in Perl (I like perl )

Will it work, doubtful as most decent networks will not route spoofed IP addresses however there are some providers out there that may or may not have incorrectly (or correctly set up and they don't care) set up their networks

This seems technical and challenging when one can simply use a proxy and/or VPN. You must be hellbent on accomplishing some really illicit task with automation. Good luck OP!

I don't even think you can spoof TCP.
The socket will init and send a SYN, then the server will return the SYN-ACK to the spoofed IP, which is not yours but someone else on the internet, your socket will never fully establish?
I may be wrong though...

Even so, as fatboy said, most provider won't let you spoof your Internet IP address
