  • XMap

    XMap is an open-source network scanner that enables researchers to perform Internet-wide IPv6 & IPv4 network research scanning efficiently. XMap is reimplemented and improved thoroughly from ZMap and is fully compatible with ZMap, armed with the “5 minutes” probing speed and novel IPv6 scanning techniques. XMap can be used to conduct large-scale IPv6 network scanning for device discovery and security assessments and help us gain more insights into the IPv6 networks.
