How I Built a Dual-Stack Enterprise Network and Demonstrated an IPv6 Hijack Attack (with Full Mitigation)

Short summary

Hands-on tutorial demonstrating IPv6 SLAAC vulnerabilities in dual-stack networks via man-in-the-middle attacks. Author built a multi-VLAN topology in GNS3 with Cisco routers and launched a Python-based IPv6 hijack from Kali Linux to show how unprotected IPv6 bypasses hardened IPv4 controls. Complete mitigation using RA Guard and layer-2 security controls is detailed with configurations applicable to production networks.

  • •Built full dual-stack enterprise network lab in GNS3 with Cisco IOSv/IOSvL2 and detailed addressing
  • •Demonstrated IPv6 SLAAC hijack attack using Python/Scapy from Kali Linux; no privileges required
  • •Showed complete mitigation with RA Guard and parallel ACL policies; directly implementable in production

Generated with AI, which can make mistakes.
