SlowDNS DNS Layout

SlowDNS depends on the correct relationship between the public host and the delegated tunnel domain.

Overview

SlowDNS needs two related names: the public host that resolves to the VPS, and the delegated tunnel domain that points to that host via an NS record.

Example layout

If you install with:

  • Public hostname: dns.example.com
  • Delegated tunnel domain: slowdns.example.com

Then your DNS should look like this:

A   dns.example.com        1.2.3.4
NS  slowdns.example.com   dns.example.com

Verify DNS

dig +short A dns.example.com
dig +short NS slowdns.example.com

The A lookup should return the VPS IPv4. The NS lookup should return the public hostname that serves the delegated tunnel zone.

Common failure cases

  • The public host has no A record.
  • The delegated tunnel domain points to the wrong nameserver host.
  • The client is configured with the public host instead of the delegated tunnel domain.
