dns manager

Simple dns manager, allows you to easily define your own domains handled by it.

Overview

By default, dnsman reads /etc/dnsman/records and responds to requests by choosing the most specific entry.

# /etc/dnsman/records

# Upstream/fallback servers
nameserver 8.8.8.8
nameserver 8.8.4.4

# Proxy example.com to these, ordered by priority
ns .example.com 1.1.1.1
ns .example.com 1.0.0.1

# Route the .dev tld to localhost
a .dev 127.0.0.1
txt .domain.com "text entry"
txt .domain.com "includes""quotes"

Upstream/fallback server

Normally, dns servers will respond with an upstream server to the client and let the client make a new request to that server. This server will pretend to be all-knowing, or at least for the first hop, forwarding the request to a known upstream server if it doesn't know.

Matching

Matching records is performed by the tailing end of the request. Assume requests always have a dot prepending their least signigicant section.

| Config | Request | Matches | | ------------ | ---------------- | ------- | | .dev | mydomain.dev | yes | | .dev | example.dev | yes | | example.com | example.dev | no | | example.com | example.com | yes | | example.com | 1example.com | yes | | example.com | sub.example.com | yes | | example.com | sub.1example.com | yes | | .example.com | example.com | yes | | .example.com | 1example.com | no | | .example.com | sub.example.com | yes | | .example.com | sub.1example.com | no |
