Key Features
- Cryptographic verification of DNS data
- Prevents DNS spoofing and cache poisoning attacks
- Uses digital signatures and public key cryptography
- Supports secure delegation and zone signing
- Enhances overall trustworthiness of DNS lookups
Pros
- Significantly improves security and trust in DNS queries
- Reduces risk of malicious redirects and man-in-the-middle attacks
- Widely supported by major DNS providers and registries
- Strengthens the integrity of internet infrastructure
Cons
- Implementation can be complex and requires proper management of keys
- Not universally adopted, leading to potential fallback issues
- Adds computational overhead for DNS resolution processes
- Potential for misconfiguration if not managed correctly
