Network configuration for Cloud Print

Your network must allow the Cloud Print client to reach its servers. This page covers the domain names, IP address ranges, and ports you need to allow.

​
Required domain names

Your Cloud Print client needs to resolve the following addresses:
  • api.printnode.com
  • app.printnode.com
  • host2b.printnode.com
  • client.printnode.com
  • lon1.printnode.com
  • central.printnode.com
  • rdga3b.printnode.com
  • byfa3b.printnode.com
While the IP address ranges for these domains are fixed, the specific IP address a domain points to can change at any time.

​
IP address ranges

The domains listed above can resolve to an IP address within any of these ranges:
CIDR blockRange
5.10.27.32/285.10.27.33 — 5.10.27.46
5.10.23.32/275.10.23.33 — 5.10.23.62
94.228.44.128/2894.228.44.129 — 94.228.44.142

​
Required ports

The Cloud Print client sends data outbound on ports 443 and 6123. Ensure these ports are open for outbound connections.

​
Testing your connection

To verify connectivity, open a web browser on the machine running Cloud Print and navigate to your portal.
If the page does not load, there is a connection problem between your computer and the Cloud Print servers.

​
Troubleshooting connection issues

If the connection test fails, you can trace the network route:
  • Windows: Open Command Prompt and run tracert api.printnode.com
  • macOS / Linux: Open Terminal and run traceroute api.printnode.com
If your browser can reach the portal but the Cloud Print client still cannot connect, contact the support team.
What are ports?Ports are virtual endpoints for network connections. They help your computer route incoming and outgoing data to the correct program or service.What is tracert / traceroute used for?These commands trace the path data takes from your computer to a destination on the internet, helping you identify where a connection problem occurs.
