Purpose Of The DNS Dig Tool
The DNS Dig tool performs a focused DNS lookup for one record type at a time. It shows how the hublist server resolves the selected hostname, which is important because generated hublist files rely on stable public names.
Fields And Controls
- Host Or Address: Enter the hub hostname or hub URL. The hostname is extracted and normalized.
- Record Type: Choose A, AAAA, CNAME, MX, NS, SOA, or TXT depending on what you need to inspect.
- Raw Output: Shows the dig-style response for administrators and troubleshooting.
What Each Record Means
- A: IPv4 address used by most DC++ clients.
- AAAA: IPv6 address for clients and networks that support IPv6.
- CNAME: Alias that must eventually resolve to usable A or AAAA records.
- NS/SOA: Authoritative DNS configuration and zone ownership.
- MX/TXT: Usually mail or verification records; useful for context but not normally hub connectivity.
Common Errors
NXDOMAIN means the name does not exist. NOERROR with no answers means the name exists but not for the chosen record type. Stale answers can appear until TTL expires, so wait after DNS changes before assuming clients are wrong.
