DNS-over-HTTPS

This is a read-only/monitoring "registrar". It does a DNS NS lookup to confirm the nameserver servers are correct. This "registrar" is unable to update/correct the NS servers but will alert you if they are incorrect. A common use of this provider is when the domain is with a registrar that does not have an API.

Configuration

To use this provider, add an entry to creds.json with TYPE set to DNSOVERHTTPS.

creds.json

{
  "dohdefault": {
    "TYPE": "DNSOVERHTTPS"
  }
}

The DNS-over-HTTPS provider defaults to using Google Public DNS however you may configure an alternative RFC 8484 DoH provider using the host parameter.

Example:

creds.json

{
  "dohcloudflare": {
    "TYPE": "DNSOVERHTTPS",
    "host": "cloudflare-dns.com"
  }
}

Some common DoH providers are:

• cloudflare-dns.com (Cloudflare)

• 9.9.9.9 (Quad9)

• dns.google (Google Public DNS)

Metadata

This provider does not recognize any special metadata fields unique to DOH.

Usage

An example configuration:

dnsconfig.js

var REG_MONITOR = NewRegistrar("dohcloudflare");

D("example.com", REG_MONITOR,
  NAMESERVER("ns1.example.com."),
  NAMESERVER("ns2.example.com."),
END);

NOTE: This checks the NS records via a DNS query. It does not check the registrar's delegation (i.e. the Name Server: field in whois). In theory these are the same thing but there may be situations where they are not.
