Many servers and network devices like routers and switches provides features
like ACLs, IP Filters, Firewall rules and so on to give access to their Services
only to particular network addresses (usually Administrator's workstations).The
main purpose of this program is to scan for IP restrictions set for a particular
service on a host. It combines "ARP Poisoning" and "Half-Scan"
techniques and tries totally spoofed TCP connections to the selected port of
the target. IRS is not a port scanner but a "valid source IP address"
scanner for a given service.
