Query one DNS record type for a public DC++ hub hostname from the same server that publishes the Direct Connect hublist.

Purpose

The tool performs a bounded dig-style lookup for A, AAAA, CNAME, MX, NS, SOA, or TXT data and separates response metadata from answer, authority, and additional sections.

When To Use It

  • Verify a changed A or AAAA record after moving a hub.
  • Follow a CNAME chain that points clients to an unexpected address.
  • Inspect TTL and authoritative DNS data while investigating stale answers.

Reading The Results

Answer rows show the selected record values. TTL indicates how long a resolver may cache them. Authority rows can identify the zone responsible for an answer, while status and query timing help distinguish an empty answer from a failed lookup.

Limitations

A correct DNS answer does not prove that an NMDC, NMDCS, ADC, or ADCS service accepts connections. Cached answers can remain until TTL expiry, and another resolver or client network can temporarily see different data.

For query examples and DNS recovery steps, open DNS Dig.

Hub DNS Dig Tool

Run a dig-style DNS lookup for public hub hostnames and inspect A, AAAA, MX, NS, SOA, TXT, or CNAME records.

Enter a public hostname, IP address, or hub-style address such as dchub://example.com:411.
Choose the DNS record type to query.
