Dynamic IP setup

ScoutDNS registers networks by public WAN IP. Most business connections have a static IP, perfect. If your ISP gives you a dynamic IP, you can register a dynamic-DNS hostname instead, and ScoutDNS will poll it to keep your network registration current.

Supported providers

Any dynamic-DNS provider that publishes a regular DNS A record works. Common options:

• No-IP
• ChangeIP
• DynDNS
• FreeDNS

You’ll need an account with one of these and a hostname that resolves to your current public IP.

Configure the network in ScoutDNS

1. Open Sites → [your site] → Networks.
2. Either click an existing network’s Edit Network button or click New Network.
3. In the Net Address field, enter your fully qualified dynamic-DNS hostname (e.g. acme-hq.ddns.net) instead of a literal IP.
4. Save.

The ScoutDNS Dynamic DNS updater service starts polling immediately, resolves the hostname, and registers the resulting IP. Refresh the Campus / Sites view to see the resolved IP.

How the sync works

[!NOTE] ScoutDNS’s updater runs in the cloud and only watches your provider’s DNS record. It does not install anything on your network and does not push updates to your router.

You still need the provider’s client-side updater (typically a small daemon on your router or a host on the network) to push your current public IP to the dynamic-DNS service. Once that piece is in place, ScoutDNS picks up the change from the public DNS record automatically.

Troubleshoot

• ScoutDNS shows the wrong IP, confirm the dynamic-DNS hostname resolves to your actual current public IP from an external network (e.g. nslookup acme-hq.ddns.net 8.8.8.8). If it doesn’t, the provider’s updater isn’t running or has stale credentials.
• No queries arriving even though the IP looks right, wait a few minutes for the updater service’s poll cycle, then verify with the Quickstart checklist.

If neither helps, open a support ticket.
