Is dns-connect free?

Yes, completely free. No credit card, no hidden fees, and no limits on IP updates.

What is dynamic DNS?

Most home internet connections use an IP address that changes periodically. Dynamic DNS maps a consistent hostname — like home.dns-connect.org — to your current IP and updates it automatically whenever it changes.

Which platforms are supported?

The desktop client runs on Windows 10 or later and macOS 13 or later. Any router that supports the standard DynDNS protocol with a custom server also works — no app required.

Should I use the desktop app or router DDNS?

Both do the same job — they detect when your public IP changes and update your dns-connect subdomain automatically. Here's how to decide:Use the desktop app if:
  • You want the simplest setup
  • You're not sure whether your router supports custom DDNS
  • Your router is a standard consumer device
Use router DDNS if:
  • Your router supports entering a custom DDNS server address
  • You want your IP to stay updated even when all your computers are off
  • You are running open-source firmware such as DD-WRT or OpenWrt
You only need one — running both on the same subdomain is redundant.

Does my router support custom DDNS?

dns-connect uses the standard DynDNS update protocol. For your router to work with dns-connect, it must allow you to enter a custom DDNS server address — not just select from a preset list of providers like No-IP or DynDNS.Most consumer routers do not support custom server entry, even if they have a DDNS feature. Routers running open-source firmware such as DD-WRT or OpenWrt, and some enterprise or prosumer devices, typically do allow this.If you are unsure, check your router's DDNS settings and look for a "Custom" or "User-defined" server option. If it only shows a fixed list of providers, it is not compatible — use the desktop app instead.

How do I set up dns-connect on a compatible router?

Find the DDNS or Dynamic DNS section in your router's admin panel and enter the following:
Service typeCustom / DynDNS
Serverdns-connect.org
UsernameYour dns-connect email address
PasswordYour DDNS token (generated from the dashboard)
HostnameYour full subdomain (e.g. home.dns-connect.org)
Refer to your router's documentation for the exact steps — the location of DDNS settings varies by manufacturer and firmware.

How quickly does my IP update?

The desktop client detects IP changes within minutes and updates your DNS record immediately. Most changes propagate across the internet within a few seconds.

Can I use the same subdomain on multiple devices?

No — each device should have its own subdomain. If two devices update the same record they will overwrite each other.

What happens if I close my laptop?

The app resumes polling when the machine wakes from sleep. Your DNS record may be temporarily stale while the machine is asleep or off.

Will my subdomain be deleted if I stop using it?

Subdomains that have not received an IP update in 12 months are automatically released. You will receive email warnings before deletion.

Can I delete a subdomain myself?

Yes. Go to your dashboard, find the subdomain in the list, and click Remove.

Does dns-connect support IPv6?

Not currently. dns-connect creates A records (IPv4) only.

Is the desktop app open source?

Yes. The full source code is available on GitHub.

Do I need technical knowledge to set it up?

No. Download the app, log in, and it runs automatically in the background. The guide walks you through every step.
