How to use DNS Lookup Parser

  1. 1

    Run dig or nslookup

    Run a query such as dig example.com ANY and copy the answer section.

  2. 2

    Paste the output

    Paste it into the tool, or load the sample.

  3. 3

    Read the records

    Each record is normalized into name, TTL, class, type and value.

  4. 4

    Check the warnings

    Unusually high TTLs (over 24 hours) and input with no parseable records are flagged.

Questions and answers

Does it perform the DNS lookup?
No. It parses output you already have, so it works for internal resolvers and split-horizon DNS that a public tool cannot reach.
Which record types are supported?
A, AAAA, CNAME, MX, TXT and NS records written as dig answer lines (host, optional TTL, IN, type, value). Other record types, and nslookup's Name/Address layout, are skipped.

Use it as an API

DNS Lookup Parser is also callable as a free HTTP JSON API at https://aidevhub.io/api/dns-lookup/ — GET with query parameters or POST with a JSON body, no authentication, CORS enabled, fair use (abusive traffic is throttled at the edge; there is no per-request quota header). Responses return { ok, tool, result, meta }. 

curl -s -X POST https://aidevhub.io/api/dns-lookup/ \
  -H "Content-Type: application/json" \
  -d '{"output":"example.com. 300 IN A 93.184.216.34\nexample.com. 300 IN MX 10 mail.example.com."}'
