About the data

IX Report lists every internet exchange in PeeringDB and compares two views of who is connected to each one: the member list the exchange publishes itself, and the networks that say they're there in PeeringDB.

Where each column comes from

• Members is the number of networks (by ASN) on the exchange's own published member list. Most exchanges publish it as an IX-F Member Export, a standard JSON format; some only have a web page, which is read with a small custom rule.
• PeeringDB is the number of networks with a connection to the exchange in PeeringDB. Exchange details, prefixes, facilities and network names on each exchange page come from PeeringDB too.
• A network flagged Not in PeeringDB is on the exchange's own list but doesn't have a PeeringDB record for that exchange. PeeringDB only is the reverse.

PeeringDB data was last downloaded 2026-10-02 21:32 UTC. Member lists are re-read on every update. If a list can't be read, the last good copy is kept for up to a week and marked as older.

Adding an exchange's member list

The quickest way is for the exchange to put its IX-F export URL in its PeeringDB record (under the peering LAN's "IX-F Member Export URL", visible to the public); it's picked up on the next update. Links registered in Euro-IX's IX-F database (IXPDB) are used too, when PeeringDB doesn't have one. Otherwise, send the URL of the member list page and we'll add a rule for it.
