Internet Peering

CNX offers Internet Peering, providing participating ISPs and network operators access to a wide variety of networks connected to the CNX IX platform through a single connection.

This approach is cost-efficient, reduces reliance on transit, and simplifies network management and scaling. The peering LAN supports both IPv4 and IPv6 natively and is actively monitored 24×7 by our Network Operations Center (NOC).

Why connect?

• Cost savings – reduce transit spend by exchanging traffic locally.
• Lower latency – keep Cambodian traffic in Cambodia, improving user experience.
• Resilience – additional paths for redundancy during outages.
• Scalability – simple upgrades without renegotiating multiple bilaterals.
• Access to ecosystem – content providers, cloud, gaming, and financial services are all present.
• IPv6 native – ready for modern networks.
• Digital sovereignty – ensure domestic traffic remains subject to Cambodian law, not foreign jurisdictions.

How to connect

You can connect in two ways:

1. Cross-connect (XC) in selected data centers, directly to the CNX switch fabric.
2. Metro fiber handoff from one of our partner providers.

CNX ensures the operation of the exchange fabric. Members are responsible for their own equipment and the cross-connect or metro circuit to our handoff point.
