Cambodia's national internet exchange fabric.

One connection. Access to every Cambodian network. Local traffic stays local, latency drops, and transit costs fall.

CNX operates Cambodia's national internet exchange across six independent data centres in Phnom Penh, interconnecting ISPs, content providers, cloud networks, and government institutions on a shared L2 fabric. One port gives direct access to every member on the exchange — no transit, no intermediary.

CNX also hosts DNS root server instances at the exchange — supported by PCH, APNIC, and Netnod — keeping the root lookup step inside Cambodia. More in the DNS section.

Exchange Port

One physical port gives you both public peering on the shared exchange LAN and private network interconnects (PNI) via VLAN — two capabilities, one handoff, no additional hardware.

Peering PNI
Colocation

Equipment hosting at CNX partner facilities. Members colocate transmission and server equipment to sit directly on the exchange fabric.

Colocation
Cross-Connects

Physical fiber between co-located parties, to transit providers, or to the metro network. CNX facilitates cross-connects within its facilities and to partner metro carriers.

Technical Reference

CNX operates mandatory route servers with RPKI-based prefix filtering and AS-path validation. All members peer with the route servers — this is how routing integrity is maintained across participants. Members control their own route distribution via BGP communities.

Configuration guides are available for Cisco, Huawei, and BIRD. The looking glass gives real-time visibility into routes and session status.

Policy

The Technical Requirements document defines the operational baseline for all members — port configuration, BGP session parameters, and acceptable use. It is the primary reference for anyone connecting to CNX.

The peering and route-server policy and general terms and conditions are also in the policy section.
