This is regular hping2 with a few extra features:

• -6 - required for ipv6 destinations
• --pps
• --bps - set outgoing pps/bps rates. Return packets are not processed in these modes.
• -flood-send packets as soon as posible.
• random source ip and dest ip support ipv6

Example:

root@koszik-vps:~# ./hping6 ns1.atw.hu -6 -2 -p 53 -k  -s 1583 --traceroute

TCP flood attack with random source ip with ipv6:

root@testlab:~# ./hping6 2022:1:1:1::2 -6 --rand-source --flood

`2022:1:1:1::2` is the ipv6 address you want to attack
