Windows v2.0.0

Native Windows client with system tray icon. Runs as a background process and updates your DNS records automatically when your public IP changes. Supports all record types (A/AAAA).

Installation

1. 1Run the MSI installer and accept the UAC prompt. The app runs in the system tray — lightweight, built with a modern, memory-safe language, minimal resource usage. Supports 11 UI languages with a consistent look and feel on both Windows and macOS.
2. 2The system tray icon appears. Click it → Settings.
3. 3Enter your No-IP.pl login and password.
4. 4Enter the hostname(s) you want to keep updated (e.g. myhome.no-ip.eu). The hosts must already exist in your No-IP.eu account panel. Click Save.
5. 5Status turns green. Your DNS records are now updated automatically on every IP change.

macOS v2.0.0

Universal binary (Apple Silicon + Intel). Runs as a login item in the menu bar, no terminal required.

Installation

1. 1Open the DMG and drag No-IP Client.app to /Applications.
2. 2The app is not code-signed (no Apple Developer ID). On first launch, macOS Gatekeeper will block it. Fix: right-click No-IP Client.app → Open → click Open in the security dialog. This only needs to be done once. Alternatively: System Settings → Privacy & Security, scroll down and click Open Anyway.
3. 3Click the menu bar icon → Preferences. Enter your credentials.
4. 4Enter the hostname(s) you want to keep updated (e.g. myhome.no-ip.eu). The hosts must already exist in your No-IP.eu account panel. Click Save.
5. 5Optional: enable Launch at Login in Preferences so it starts automatically.

Linux x86-64

Lightweight static binary — no dependencies, no installer. Uses the native no-ip.eu UDP protocol (port 7777): lighter than HTTPS, works through most firewalls. Good fit for servers, VMs, and automated setups.

Usage

Quick start

1. 1Download and make executable:
   
   wget -O /usr/local/bin/noip.client https://no-ip.eu/progs/noip.client-x64 chmod +x /usr/local/bin/noip.client
2. 2Test with a single update:
   
   noip.client -u user@example.com -p yourpassword -d myhome.no-ip.eu
3. 3Start as daemon (updates every 5 min in background):
   
   noip.client -u user@example.com -p yourpassword -d myhome.no-ip.eu -b 5 &
4. 4To start automatically after reboot, add to crontab:
   
   crontab -e # Add: @reboot /usr/local/bin/noip.client -u user@example.com -p yourpassword -d myhome.no-ip.eu -b 5
   Note: on some systems @reboot fires before the network is up. Because the daemon retries every 5 minutes, it will connect automatically on the first successful attempt after boot.
5. 5systemd unit file and SysV init script are in preparation — not yet included in this release. For now use cron as shown above.

Linux ARM / Raspberry Pi

ARMv7+ binary. Works on Raspberry Pi (all models), Orange Pi, Banana Pi, and any ARMv7+ Linux system. Identical interface to the x64 version.

Quick start

1. 1
   wget -O /usr/local/bin/noip.client https://no-ip.eu/progs/noip.client-arm chmod +x /usr/local/bin/noip.client
2. 2Test with a single update:
   
   noip.client -u user@example.com -p yourpassword -d mypi.no-ip.eu
3. 3Start as daemon (updates every 5 min):
   
   noip.client -u user@example.com -p yourpassword -d mypi.no-ip.eu -b 5 &
4. 4Auto-start after reboot via crontab:
   
   crontab -e # Add: @reboot /usr/local/bin/noip.client -u user@example.com -p yourpassword -d mypi.no-ip.eu -b 5

Router (built-in DDNS)

Most routers support the DynDNS protocol natively. No software to install — configure once, works forever.

Works with any DynDNS2-compatible client. No-IP.eu implements the standard DynDNS2 protocol — the same one used by most routers, ddclient, inadyn, and other DDNS tools. Set the update server to update.no-ip.pl and your no-ip.eu credentials. Our native Linux/C client uses an optimised UDP protocol specific to no-ip.eu — lighter and firewall-friendly compared to HTTPS.

Router-specific notes

• ASUS: WAN → DDNS → Service Provider: Custom. Paste update.no-ip.pl as the server URL.
• TP-Link: Advanced → Network → Dynamic DNS → Service Provider: DynDNS.org works. Server: update.no-ip.pl.
• MikroTik: IP → Cloud is not relevant. Use the /ip cloud script or a RouterOS script calling update.no-ip.pl via HTTP GET.
• OpenWrt: No-IP.eu is an officially supported DDNS provider in OpenWrt. Install the ddns-scripts package, select no-ip.pl from the provider list, and set the server to update.no-ip.pl. The DynDNS2 update URL is shared — it works with no-ip.eu accounts.

Docker

Use qmcgaw/ddns-updater — a well-maintained multi-provider DDNS updater. Supports No-IP protocol.

Replace myhome.no-ip.pl, This email address is being protected from spambots. You need JavaScript enabled to view it., and yourpassword with your actual credentials. The container checks your IP every 5 minutes and updates the record when it changes.

FreeBSD

Binary distribution for FreeBSD amd64. Alternatively, use the inadyn port (pkg install inadyn) with the NoIP provider.

Installation

1. 1
   tar -xzf no-ip-client-freebsd.tgz chmod +x noip.client cp noip.client /usr/local/bin/
2. 2Run a test update:
   
   noip.client -u user@example.com -p yourpassword -d myhome.no-ip.eu
3. 3Add to /etc/rc.local or create an rc.d script for automatic startup.
4. 4Daemon mode or cron @reboot — same syntax as Linux above.
5. 5Alternatively, use inadyn from ports (pkg install inadyn) — supports DynDNS2 protocol, set server to update.no-ip.pl.
