Overview

JustASRV is a managed Dynamic DNS (DDNS) service operated by SoMo Technologies. A device at each customer site reports the site's public IP address; JustASRV keeps a hostname such as acme-main.ddns.justasrv.com pointed at it.

Where to start

Getting started: the five-minute path from nothing to a working hostname.
Router compatibility: which devices work natively and which need the updater.
API reference: the update protocol, responses and limits, for anyone integrating their own client.
Troubleshooting: what each response means and how to fix it.
