## Key points

- Quantum risks to DNS may arrive sooner than expected.
- Larger DNSSEC keys could require a shift towards TCP.
- ICANN and other bodies are speeding up preparation.

## Summary

Internet governance bodies are accelerating preparations to protect the Domain Name System from future quantum computers that could break conventional encryption. ICANN CTO John Crain said the threat may arrive sooner than previously expected, bringing forward the need to make DNS security quantum-safe.

One proposed approach is to use larger DNSSEC keys, but the resulting bigger messages could exceed DNS limits and require more traffic to move from UDP to TCP. Crain said deployment is likely still a few years away, though development will speed up. The article also reports on proposed rules for regional internet registries and ICANN research into whether some top-level domains attract more scammers.
