What are the limits of DNS Zone File Validator?
Local syntax and consistency review, not an authoritative zone-load test. Supports $ORIGIN, $TTL, owner inheritance, IN class, quoted TXT chunks and parenthesized SOA. Checks A/AAAA, aliases, MX/NS targets, SOA, TTLs, duplicate RRsets and CNAME coexistence. $INCLUDE/$GENERATE and uncommon record types are explicitly reported as unsupported. Text input: 5 MB total. XML external entities and includes are disabled. No automatic local storage. Reports summarize the selected result; CSV/JSON retain complete records.
