XMap: The Internet Scanner

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.

XMap operates on GNU/Linux, macOS, and BSD. XMap currently has implemented probe modules for ICMP Echo scans, TCP SYN scans, UDP probes, and DNS scans (stateless, stateful, or address-spoofing).

With banner grab and TLS handshake tool, ZGrab2, more involved scans could be performed.

Installation

The latest stable release of XMap is version 2.0.0 and supports Linux, macOS, and BSD. We recommend installing XMap from HEAD rather than using a distro package manager (not supported yet).

Instructions on building XMap from source can be found in INSTALL.

Installing from docker: docker pull liii/xmap:latest

Usage

A guide to using XMap can be found in our GitHub Wiki.

Simple commands and options to using XMap can be found in USAGE.

Check how to use DNS probing modules in Issue #11.
