reroute the incoming packets to the attacking ip
burn down your house so you can't get hit with dos attacks
better yet, set yourself on fire and burn to death so you can't get hit at all!
What if I build a time machine and go back and murder Bill gates so that internet never exists?
Call your ISP, tell them your current IP and ask them to change it because you're being hit with a denial of service attack.
If you murdered bill gates the internet would still exist, though everyone would use macs to get on it.
Ill kill steve jobs too then
Then you would not be here because internet doesn't exist and thus you would have never asked this question on the internet that doesn't exist which means you never went back in time which means Bill Gates was never killed which means the internet is created but then you would ask this question thus you will be set in a never ending paradox.
