Rolling out IPv6 quietly on a web hosting platform

Summary

Manuel Schmitt reports on the gradual IPv6 rollout for all existing and new web hosting packages and their domains. Since December 2018, all old and new web hosting packages had been reachable via IPv6. The rollout covered all associated domains.

Ideas

  • A quiet, gradual rollout limits errors before a feature is advertised publicly.
  • IPv6 can become transparent for customers when DNS, routing and web servers are prepared together.
  • Shared IPv6 addresses are an intermediate step before dedicated addresses.

Insights

  • An infrastructure change that goes unnoticed can be a sign of good preparation.
  • Dual stack requires operational maturity on the platform, not just an additional DNS record.

Facts

  • Dedicated IPv6 addresses were not offered at that time.

Recommendations

  • Monitor IPv4 and IPv6 separately from external networks.
  • Explicitly check firewall, logs and abuse detection for both protocol families.

Managing IPv6 reverse DNS with PTR, CNAME and delegated networks

Manuel Schmitt describes joint IPv4 and IPv6 reverse DNS management with search, CSV export and delegation of entire IPv6 networks. The editor supported PTR, CNAME and NS records for IPv6. CSV exports also contained addresses in binary notation.

RFC 8200: The IPv6 base standard

RFC 8200 replaces the original IPv6 specification and consolidates the matured base standard. An Internet Standard can become more precise through operational experience without changing its architecture. Deploying IPv6 requires full support in security and monitoring.
