Wellington · New Zealand
PeeringDB records two internet exchanges in Wellington, WLG-IX (Wellington NZ) with 24 participants and WIX-NZ with 18, alongside 12 colocation facilities holding 81 networks. WLG-IX is the better connected of the two. An address geolocating to Wellington shows where an operator registered the block rather than where a device sits.
Internet exchanges in Wellington
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 |
|---|---|---|
WLG-IX (Wellington NZ) | 24 | none in the registry |
WIX-NZ Wellington Internet Exchange | 18 | none in the registry |
Exchange records: PeeringDB.

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 Wellington IP address tells you
Wellington's recorded peering divides between two exchanges. WLG-IX (Wellington NZ) has 24 participants and WIX-NZ, the Wellington Internet Exchange, has 18, for 42 in all. Colocation carries about twice that, 81 networks across 12 facilities, and two buildings hold more than half of them, Spark Wellington Central (Featherston) with 22 and Xtreme Networks - Wellington DC with 21. Counts fall away quickly below those, to seven each at the Chorus Wellington and Courtenay Place exchanges and none at Chorus Johnsonville. Neither exchange has a carrier ASN attached, and the carrier data behind this page names no New Zealand mobile operator.
A database that places an address in Wellington is not reporting where the device is. An operator announces a block from a registry record that carries a single address for the whole allocation, and mobile traffic leaves through a handful of gateways whose location has little to do with the subscriber's. Geolocation providers copy the operator's published location, so traffic from anywhere in New Zealand can resolve to Wellington while never touching WLG-IX, WIX-NZ or one of the 12 facilities the registry lists here.
The origin ASN and the netname on the specific prefix tell you more than the city field does. The ASN names the network that announced the range, and the netname shows how that network labels it, including whether it holds mobile subscribers. Neither shows that a packet crossed WLG-IX or sat in Spark Wellington Central. The 42 exchange participants and 81 facility networks describe where peering in Wellington is documented, not where a particular address is.
Questions
Which internet exchanges are in Wellington?
PeeringDB lists two. WLG-IX (Wellington NZ) records 24 participants and WIX-NZ, the Wellington Internet Exchange, records 18. Networks that peer privately inside one of the city's 12 colocation facilities rather than at either exchange are not counted in those figures.
Do New Zealand mobile carriers peer in Wellington?
The registry attaches no carrier ASN to WLG-IX or WIX-NZ, and no New Zealand mobile operator appears in the carrier data behind this page. The record is silent on the question, which is not the same as showing that mobile networks exchange no traffic in the city.
Does an IP that geolocates to Wellington mean the device is there?
No. The label comes from how the address block is registered and where its operator says the block lives. A connection that starts elsewhere in New Zealand and exits through a Wellington-registered gateway reads as Wellington to every database that follows that registration.
