GETTING DDOSED

Vpn, change mac address in router. Super easy to do add my skype romulusares I can most likely show you.

VPNs don't work if they've already got your IP... Changing MAC address has no effect on some (mainstream companies) routers. My recommendation is to tell your friend there to call his ISP and find the logs of DDoS. They may be able to file a report on the DDoSer to his ISP. However, that's very unlikely that that'll happen. If he's using a paid booter to DoS/DDoS they'll never get the true IP.

Turn your booter off and on then it resets your public IP that will stop it but before that get a VPN add me on skype if u want one of those DDoSed

To DDoS without a paid booter and to do it off your computer is flat out stupid. Exposure risk? 100%. 99/100 times if you get booted it's probably off of a paid web based booter.

Easiest fix is just request an IP change from your ISP. If they reject, just unplug your router for a bit and plug it back in. Or just wait it out (Generally never lasts longer than a few hours at most) and play SP.

If you run your own botnet and they will do all the work and your ip is hidden all the bots ip will be there but no yours and it cant be traced back to you.
