Experimental userspace toolkit implementing draft-thain-ipv8-02 — the Internet Protocol Version 8 specification. 58 modules, 35 CLI commands, 1827 tests.
Educational project. Not an official IPv8 implementation, not production networking software.
Created and maintained by Aleksei Aleinikov (@LF3551).
CLI Overview — address parsing, packet building, hex dump
Traceroute8 — linear, diamond, loop detection, multi-path
