❖ Configuration

❖ Cloudflare

Create an API token for your zone in Profile Settings. The token must have Zone::DNS::Read and Zone::DNS::Edit permissions. Zone Resource can be set to Specific Zone and set to the zone you want to update. If you would like to use this same token for all other zones, please select All Zones. Leave Client IP Address Filtering as is, and define how long this token should stay valid for in the TTL section.

The configuration for Cloudflare looks as follows:

{
    "type": "cloudflare",
    "key": "your-api-key",
    "zone": "domain.com",
    "hostname": "hostname.domain.com",
    "ttl": 1,
    "proxied": false
}

Notes:

• hostname can be set to @ if you want to update your-website.com and not a subdomain
• ttl is set to 1 for auto, otherwise it should be between 60 and 86400

❖ Namecheap

See Namecheap's Guide on enabling DDNS

The configuration for Namecheap looks as follows:

{
    "type": "namecheap",
    "password": "your-password-key",
    "host": "your-hostname",
    "domain": "your-domain.com"
}

❖ DuckDNS

Copy the token from DuckDNS profile page

The configuration for DuckDNS looks as follows:

{
    "type": "duckdns",
    "token": "your-token",
    "domain": "your-hostname.duckdns.org"
}

❖ All Together

All of the providers can be added to the same file, with multiple entries per provider as well

{
    "providers": [
        {
            "type": "cloudflare",
            "key": "your-api-key",
            "zone": "domain.com",
            "hostname": "hostname.domain.com",
            "ttl": 1,
            "proxied": false
        },
        {
            "type": "namecheap",
            "password": "your-password-key",
            "host": "your-hostname",
            "domain": "your-domain.com"
        },
        {
            "type": "duckdns",
            "token": "your-token",
            "domain": "your-hostname.duckdns.org"
        }
    ]
}
