API Reference: IPv6 Vulnerability Assessment Agent
Dependencies
| Library | Version | Purpose |
|---|---|---|
| scapy | >=2.5 | IPv6 packet crafting, NDP analysis, RA capture |
CLI Usage
sudo python scripts/agent.py \
--interface eth0 \
--known-routers "fe80::1" "fe80::2" \
--output ipv6_report.json
Functions
discover_ipv6_hosts(interface, timeout) -> list
Sends ICMPv6 Echo Request to ff02::1 (all-nodes multicast) and collects replies.
capture_router_advertisements(interface, timeout) -> list
Sniffs ICMPv6 type 134 (Router Advertisements) and extracts prefix info, DNS servers, and flags.
detect_rogue_ra(ras, known_routers) -> list
Compares RA source addresses against a known-router allowlist. Unrecognized sources flagged as rogue.
check_ipv6_firewall() -> dict
Runs ip6tables -L -n to check for IPv6 firewall rules. Empty ruleset is flagged.
check_tunnel_protocols(interface, timeout) -> dict
Sniffs for Teredo (UDP 3544), 6to4 (IP proto 41), and ISATAP tunnel traffic.
generate_assessment(interface, known_routers) -> dict
Orchestrates all checks and produces the final assessment report.
