Records without a TTL appear before any $TTL line.

ZONE_NO_DEFAULT_TTL · Severity: Warning

• WarningZONE_NO_DEFAULT_TTL

  Records without a TTL appear before any $TTL line.

  RFC 2308 section 4 asks for a $TTL line at the top of the file. Without it, loaders fall back to different defaults (the SOA minimum, the previous TTL), so the TTL of those records depends on the server software.

  Recommendation: Add a $TTL line, for example $TTL 3600, at the top of the file.
