Overview
Even if you “don’t use IPv6,” OSes often prefer it—unexpected leaks happen.
Verify
- DNS64/NAT64 accidental.
- Firewalls default allow IPv6 any-to-any.
- Public AAAA records with untested services.
Strategy
Either full dual-stack managed or explicit IPv6 disabled consistently with security sign-off—not halfway.
