FAQ

Configuration

How do I configure the client on my router?

Most modern routers (ASUS, TP-Link, Mikrotik, OpenWrt, pfSense) support the DynDNS protocol. In your router settings, find the "DDNS" or "Dynamic DNS" section and enter:

  • Provider: Custom or DynDNS
  • Server: update.no-ip.pl
  • Hostname: yourhost.no-ip.pl
  • Username: Your No-IP.pl login
  • Password: Your No-IP.pl password

What port does the No-IP client use?

The client communicates via port 7777 UDP or alternatively via HTTPS (port 443). Make sure your firewall doesn't block these outgoing ports.

How do I check if updates are working?

  1. Log in to the No-IP.pl panel
  2. Check the "Last update" column next to your host
  3. Compare the displayed IP with your actual one (e.g. via whatismyip.com)

Do you support IPv6?

Yes. You can create AAAA records for IPv6 addresses. The client automatically detects and updates both IPv4 and IPv6.

Account and Security

I forgot my password. What should I do?

Use the password reset function. You'll receive a link to set a new password at the email address you provided during registration.

Can I change my hostname?

Hostnames cannot be changed - you need to delete the old one and create a new one. Keep in mind that popular names may be taken by other users.

How long does an inactive account remain active?

Free accounts inactive for 12 months may be deleted. Hosts not updated for 30 days may be deactivated. We recommend regular login or updates.

Is my data secure?

  • Passwords are stored hashed
  • Connections encrypted with SSL/TLS
  • Servers in EU, GDPR compliant
  • Regular backups

Troubleshooting

My host is not updating. What should I check?

  1. Is the client running? - Check if the client process is active
  2. Login credentials - Make sure username and password are correct
  3. Firewall - Port 7777 UDP or 443 TCP must be unblocked
  4. Update limit - Don't update more often than every 5 minutes

My website/service doesn't work despite correct DNS

Check:

  1. Port forwarding - Is the port forwarded on your router?
  2. Local firewall - Is the system blocking incoming connections?
  3. ISP - Some providers block ports 80/443 for residential customers
  4. Double NAT - Do you have a router behind a router?

How do I forward a port on my router?

Instructions vary depending on your router model. Check your manufacturer's documentation or visit portforward.com for instructions for specific models.

"Reserved name" error

Some names are reserved and unavailable (e.g. www, mail, ftp, admin). Choose a different name.
