Why IX.NET

One relationship for peering across the middle of the country

IX.NET is one platform for eleven exchanges: six it operates and five it extends to Kansas City. You work with one team, one application process and one set of policies, whether you need a single exchange or all of them. The people running IX.NET have run KCIX since 2006.

  • Six markets

    Kansas City, St. Louis, Houston, Springfield, Des Moines and Sioux City. KCIX also reaches Minneapolis and Southfield, MI.

  • Free local ports

    No monthly port fee on any IX.NET exchange, at any speed. You pay the data center for the cross-connect.

  • Five remote exchanges

    SIX, MICE, IX-Denver, DE-CIX Dallas and DE-CIX New York, handed off locally in Kansas City.

  • Neutral

    IX.NET doesn't sell transit or colocation, so it never competes with the networks that peer on it. Every member gets the same route servers and policies.

Our exchanges

Six exchanges, free to join

Each exchange has its own peering LAN, route servers and member list, and none of them charge a monthly port fee. Connect to one or to all six.

Extensions

Five remote exchanges, one local handoff

IX.NET runs extension switches in Kansas City for five exchanges in other cities. You get a port on the remote exchange's peering LAN, handed off in Kansas City, for a port fee.

Extension network counts are from PeeringDB, September 2026. Extension fees vary by exchange because each extension has its own transport to the remote city. MICE and IX-Denver ports cost the same as connecting to those exchanges directly, and MICE ports are billed yearly. Email peering@ix.net for current pricing.

How it works

What an internet exchange does

An exchange is a shared switch in a data center. Networks connect to it once and then trade traffic directly with each other.

Direct paths

Traffic between two networks on the exchange goes straight across it, instead of through a third-party transit provider in another city.

Lower latency and cost

Shorter paths mean faster connections, and traffic you exchange here no longer counts against your transit bill.

Who can join

Any network with its own ASN: ISPs, hosting and content providers, cloud platforms, universities and enterprises.

What it costs

Ports on IX.NET's six exchanges are free; you pay the data center for the cross-connect. Extension ports carry a port fee.

Locations

Where to connect

Connect wherever your network already is. Every location gets the same ports and route servers. Buildings are listed alphabetically within each metro.

Connect

How to join

The process is the same at every exchange. Ask for several at once and we'll set them up together.

  1. Update PeeringDB

    Make sure your network's PeeringDB record is current and lists your IRR AS-SET. The route servers filter on it.

  2. Apply

    Request your port at portal.ix.net/order: choose the exchange, then the building and port speed. For an extension port, email peering@ix.net.

  3. Get your LOA

    We send a letter of authorization. Order the cross-connect from the building; the facility may charge for it.

  4. Turn up BGP

    Bring up sessions with the route servers, peer bilaterally with anyone you like, and join the members' mailing list.

Technical

Peering LANs and route servers

All fabrics use a 1500-byte MTU. Max-prefix recommendations are in each exchange's PeeringDB notes.
