IP Stack Integrity Checker Its purpose is to test the stability of an IP Stack and its component stacks (TCP, UDP, ICMP et. al.) It does this be generating random packets of the desired protocol. The packets can have tendencies. ie by default all packets have a 50% chance of having IP Options. The packets are then sent against the target machine to either penetrate its firewall rules or find bugs in the IP stack.
