IRS is a software application that acts like a "valid source IP address" scanner for a given service, not like a port scanner as many would think.

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.

IRS combines "ARP Poisoning" and "Half-Scan" techniques and tries totally spoofed TCP connections to the selected port of the target.

Requirements:

· The Winpcap Driver (will be added to your system automatically by the program's installer)
