suggestion: Consider whether IPv6 DNS auto-configuration should also be disabled for consistency.

Right now only IPv4 auto DNS is disabled via ipv4.ignore-auto-dns yes. In dual-stack setups (DNS via IPv6 RA/DHCPv6), this could lead to inconsistent DNS behavior between IPv4 and IPv6. Please decide explicitly whether ipv6.ignore-auto-dns should match this setting to avoid subtle interface-specific DNS differences.
