This guide explains a single-record DNS query and the response sections shown for a public DC++ hub hostname.
Usage
- Open DNS Dig and enter the public hostname or hub URL in Host Or Address.
- Choose a Record Type: A, AAAA, CNAME, MX, NS, SOA, or TXT.
- Select Run Dig and review response metadata, answers, authority, additional data, and bounded raw output.
Concrete Example
After changing hub.example.net to a new server, run an A query for IPv4 and an AAAA query for IPv6. If the answer still shows the former address with a TTL of 3600, a resolver may retain that answer for up to an hour after it was cached.
Interpretation
A and AAAA return connection addresses. CNAME points to another hostname that must eventually produce an address. NS and SOA describe zone authority. MX and TXT are normally contextual rather than hub connection targets. NXDOMAIN differs from NOERROR with an empty answer.
Troubleshooting
- Wrong Address: Check the authoritative zone and wait for the previous TTL.
- Empty Record Type: Query the record family actually configured for the host.
- Broken Alias: Follow the CNAME and confirm that its target has A or AAAA data.
- DNS Works, Hub Fails: Continue with TCP Connect or Protocol Test.
