Christchurch · New Zealand
PeeringDB records two internet exchanges in Christchurch, CHC-IX (Christchurch NZ) with 16 participants and CHIX-NZ with one, plus 11 colocation facilities holding 71 networks. CHC-IX is the better connected. An address geolocating to Christchurch reflects an operator's registration of the block rather than the position of a device.
Internet exchanges in Christchurch
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.
| Exchange | Participants | Registry carriers peering |
|---|---|---|
CHC-IX (Christchurch NZ) New Zealand Internet Exchange, Christchurch | 16 | none in the registry |
CHIX-NZ Christchurch Internet Exchange | 1 | none in the registry |
Exchange records: PeeringDB.
Colocation facilities
Buildings where networks put equipment. The network count is how many PeeringDB members list a presence there, which shows where capacity in the city sits.

What a Christchurch IP address tells you
CHC-IX (Christchurch NZ), filed as the New Zealand Internet Exchange, Christchurch, holds 16 of the 17 exchange participants PeeringDB records in the city, and CHIX-NZ has the remaining one. More of what the registry documents sits in colocation, 71 networks across 11 facilities, with Spark Christchurch Exchange on 16 and Computer Concepts Limited (CCL) Christchurch DC on 15. The Chorus Avonhead and Christchurch exchanges and the two Enable Networks points of interconnect carry six or seven each, while Chorus Linwood Exchange records none. No carrier ASN is attached to either exchange, and the carrier data behind this page names no New Zealand mobile operator.
An address that geolocates to Christchurch may belong to a device somewhere else entirely. Operators announce blocks from a registry record that gives one address for an allocation that can cover a whole country, and mobile subscribers reach the internet through gateways concentrated in a few sites. Databases follow the operator's own published location for the block, so a lookup can return Christchurch for a connection whose traffic never reached CHC-IX or any of the 11 buildings listed here.
Checking the origin ASN and the netname on the exact prefix gets closer to the truth than reading the city field. The ASN says which network announced the block and the netname says how that network describes it, including whether the range serves mobile subscribers. Neither result proves the traffic crossed CHC-IX or sat in Spark Christchurch Exchange. The 17 participants and 71 facility networks say where peering in Christchurch is on record, not where an address is.
Questions
Which internet exchanges are in Christchurch?
PeeringDB lists two. CHC-IX (Christchurch NZ) records 16 participants and CHIX-NZ, the Christchurch Internet Exchange, records one. Networks that peer privately inside one of the 11 colocation facilities on record rather than at either exchange do not appear in those counts.
Do New Zealand mobile carriers peer in Christchurch?
Neither CHC-IX nor CHIX-NZ has a carrier ASN attached in the registry, and the carrier data behind this page names no New Zealand mobile operator. The absence is a gap in the record rather than proof that no mobile network peers in the city.
Does an IP that geolocates to Christchurch mean the device is there?
No. The city comes from the address block's registration and the location its operator publishes. A subscriber elsewhere in New Zealand whose traffic exits through a gateway registered in Christchurch will still read as Christchurch in a lookup.
