Problems

  • !
    Unusual SOA timers
    SOA · expire 3d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 6h, retry 1h, expire 3d, negative TTL 5m.

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 1 iteration and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.
