IP Sniffer            

IP Sniffer is an easy-to-use net sniffer able to intercept packets from ISO/OSI level 3 (network). It can so handle Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Internet Control Message Protocol (ICMP), Internet Group Management Protocol (IGMP) and any higher-level protocol based on those, such as HTTP, SMTP or FTP (that are based on TCP/IP).
