Why this module exists. IPv6 is increasingly deployed in Indian enterprises as ISP and cloud-provider IPv6 native availability grows. Practitioners trained on IPv4 routinely overlook IPv6 attack surface. This module covers IPv6 security in modern networks.

The IPv6 attack surface

The single most common Indian enterprise issue: IPv6 enabled on endpoints / VMs by default, no explicit IPv6 security controls. Dual-stack hosts get IPv6 addresses, IPv4 firewalls don’t see the traffic, attack-paths become invisible.
