Your server192.0.2.53

Create a subdomain

Choose an available name with 5–63 characters and select tux.re or tux.wf.

Choose the record type, enter its target and TTL, then select Create.

Edit DNS records

Open DNS / DynDNS next to your subdomain in the account.

Use @ for the subdomain itself, or a child name such as www or _dmarc.

Enter the type, value and TTL. Save the record and allow previous caches to expire.

Set up DynDNS

Use a subdomain whose primary record is A or AAAA. Create a token and copy it immediately.

Configure a compatible client with the full hostname as username, the token as password and the HTTPS update endpoint.

Send myip explicitly when using a proxy. A good response confirms an update; nochg means the IP was already current.
