Connecting to CNX.

How to join the exchange, what you need, and where to connect.


Joining CNX
Who can connect?

CNX membership is open to all organisations that have their own internet resources — an ASN and IPv4 or IPv6 address space.

How do I get started?

Contact our NOC team or go straight to the sign-up page for the necessary paperwork.

Services
What does a port give me?

One physical port provides both public peering on the shared exchange LAN and private network interconnect (PNI) via VLAN — two capabilities on a single handoff.

What community services are included?

All ports include free access to DNS root servers, RPKI validator, route servers and looking glass. See the full list at community services.

Where and how to connect
Where can I connect?

CNX is a distributed exchange across multiple data centres in Phnom Penh. You can connect at any location. See our list of locations for details on how to connect at each site.

Which cable network providers can I use?

At locations with an outdoor ODF you can use any licensed cable network provider, or bring your own cable if you have the necessary regulatory permissions.

What equipment is required?

You need a router that supports BGP4 and a compatible fiber transceiver (SFP, SFP+, or QSFP28). CNX carries approximately 120,000 routes — ensure your hardware can handle the table size and traffic volume. When in doubt, ask your vendor or our NOC team.

What port speeds are supported?

1 GE, 10 GE, and 100 GE single-mode fiber ports. Link aggregation is supported.

Costs
What does it cost?

CNX charges for switch ports only — not for peering services or traffic volume. See the full price list.

Are there cross-connect charges?

There are no cross-connect charges when connecting directly to the exchange via our outdoor ODF. Data centre cross-connect fees, if any, are charged by the facility. CNX cross-connect charges apply only for connections between co-located equipment within our installation.
