SI6 Networks' IPv6 Toolkit
A security assessment and troubleshooting tool for the IPv6 protocols
The SI6 Networks' IPv6 toolkit is a set of IPv6 security/trouble-shooting tools, that can send arbitrary IPv6-based packets.
Latest release
The SI6 Networks' IPv6 toolkit v1.3.4 is available at: ipv6-toolkit-v1.3.4.tar.gz. A GPG-signed copy of the toolkit is available at: ipv6-toolkit-v1.3.4.tar.gz.gpg.
This release includes:
- A new tool, address6, to analyze IPv6 addresses
- IPv6 host-tracking support in the scan6 tool
- Minor bug fixes
Supported platforms
The following platforms are supported: FreeBSD, NetBSD, OpenBSD, Linux, and Mac OS.
