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 |
