Abstract
XMap is a fast network scanner designed for performing Internet-wide IPv6 & IPv4 network research scanning. XMap is reimplemented and improved thoroughly from ZMap and is fully compatible with ZMap, armed with the “5 minutes” probing speed and novel scanning techniques. XMap is capable of scanning the 32-bits address space in under 45 minutes. With a 10 gigE connection and PF_RING, XMap can scan the 32-bits address space in under 5 minutes. Moreover, leveraging the novel IPv6 scanning approach, XMap can discover the IPv6 Network Periphery fast. Furthermore, XMap can scan the network space randomly with any length and at any position, such as 2001:db8::/32-64 and 192.168.0.1/16-20. Besides, XMap can probe multiple ports simultaneously.
In @Pentester Academy TV, I presented the IPv6 network scanner XMap with @DamianGoh13. New features are coming.
