Dynamic DNS (DDNS) keeps a hostname pointed at an IP address that changes. It’s perfect for home servers, game servers, surveillance cameras, and anything behind residential internet.

​
How it works

  1. Your device periodically tells Stackryze its current public IP
  2. Stackryze updates the matching A / AAAA record
  3. The world keeps resolving your hostname to the live IP

​
Set up dynamic DNS

1

Create a DDNS token

Open Settings → API → Create token with the ddns:write scope.
2

Add the records to your zone

In the zone where you want DDNS, create an A record with the placeholder value 0.0.0.0. Stackryze will treat it as a DDNS target.
3

Send updates

The DDNS endpoint is simple:
curl https://ddns.stackryze.com/update \
  -d "host=home.example.com" \
  -d "token=$STACKRYZE_DDNS_TOKEN"
Stackryze auto-detects your public IP from the request source if you don’t supply one.

​
Compatibility

The Stackryze DDNS endpoint speaks the de-facto nic/update protocol, so the same clients that work with dyndns.org, no-ip.com, and afraid.org work with Stackryze:
ClientURL
ddclientprotocol=dyndns2 server=ddns.stackryze.com
inadyn--provider dyndns2@ddns.stackryze.com
ddns-goCustom provider, URL: https://ddns.stackryze.com/update

​
IPv6

Stackryze DDNS supports IPv6 out of the box. Send the ipv6 parameter: 
curl https://ddns.stackryze.com/update \
  -d "host=home.example.com" \
  -d "ipv6=2001:db8::1" \
  -d "token=$STACKRYZE_DDNS_TOKEN"
