Configuration

Example

{
  "settings": [
    {
      "provider": "freedns",
      "domain": "sub.domain.com",
      "token": "token",
      "ip_version": "ipv4",
      "ipv6_suffix": ""
    }
  ]
}

Compulsory parameters

  • "domain" is the domain to update. It can be example.com (root domain) or sub.example.com (subdomain of example.com).
  • "token" is the randomized update token you use to update your record

Optional parameters

  • "ip_version" can be ipv4 (A records), or ipv6 (AAAA records) or ipv4 or ipv6 (update one of the two, depending on the public ip found). It defaults to ipv4 or ipv6.
  • "ipv6_suffix" is the IPv6 interface identifier suffix to use. It can be for example 0:0:0:0:72ad:8fbb:a54e:bedd/64. If left empty, it defaults to no suffix and the raw public IPv6 address obtained is used in the record updating.

Domain setup

This integration uses FreeDNS's v2 dynamic dns interface, which is not shown by default when you select Dynamic DNS from the side menu. Instead you must go to freedns.afraid.org/dynamic/v2/ and enable dynamic DNS for the subdomains you wish and you will then see a url like https://sync.afraid.org/u/token/ for each enabled subdomain.
