Mombasa · Kenya
PeeringDB records three internet exchanges in Mombasa holding 93 peering participants between them. LINX Mombasa is the best connected with 52, ahead of KIXP-Mombasa at 40 and Asteroid Mombasa at one. Two colocation facilities account for 40 networks. An address geolocating to Mombasa shows where an operator registered the block, not where the device sits.
Internet exchanges in Mombasa
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 |
|---|---|---|
LINX Mombasa | 52 | none in the registry |
KIXP-Mombasa | 40 | none in the registry |
Asteroid Mombasa | 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.
| Facility | Networks present | Address |
|---|---|---|
| SEACOM Mombasa CLS | 31 | Swahili Cultural Centre P. O. Box 85729 |
| Telkom - Telephone House - Mombasa | 9 | Mombasa Telephone House Moi Avenue |
What a Mombasa IP address tells you
LINX Mombasa holds 52 of the 93 peering participants PeeringDB records in the city and KIXP-Mombasa another 40, with Asteroid Mombasa down at one. Facility numbers run smaller than the exchange ones, at 40 networks across two buildings, 31 of them in SEACOM Mombasa CLS and nine in Telkom - Telephone House - Mombasa. Recorded peering in Mombasa therefore concentrates in the exchanges rather than in colocation space. No Kenyan mobile operator appears in the carrier registry, so none of the three exchanges has a mobile ASN matched against it.
An address that a database places in Mombasa need not be a device in Mombasa. An operator registers a block once, with one address standing for the whole allocation, and the prefixes under it carry that location wherever the record is copied. Mobile networks route subscriber traffic through a handful of gateways, so a single exit address can cover users spread over a wide area. Geolocation providers follow the location the operator published, and a phone connected elsewhere in Kenya can still return Mombasa in a lookup.
Checking the origin ASN and the netname on the specific prefix says more than the city field does. The ASN names the network that announced the block, and the netname often shows whether the operator assigned that range to mobile subscribers or to fixed circuits. The 93 participants across the three exchanges and the 40 networks in the two facilities tell you which networks are present in Mombasa, not where any of their users sit.
Questions
Which internet exchanges are in Mombasa?
PeeringDB lists three. LINX Mombasa records 52 participants, KIXP-Mombasa 40 and Asteroid Mombasa one, for 93 in the city. Networks that peer privately inside a facility instead of at an exchange are not counted, so the figure describes documented peering rather than all traffic exchanged locally.
Do Kenyan mobile carriers peer in Mombasa?
The carrier registry contains no Kenyan mobile operators, so no mobile ASN is matched to LINX Mombasa, KIXP-Mombasa or Asteroid Mombasa. The record is silent on the question rather than negative, and a carrier can exchange traffic in the city without any of it appearing in PeeringDB.
Does an IP that geolocates to Mombasa mean the device is there?
No. The label follows the address block's registration and the operator's own published location. Because mobile traffic leaves through a few gateways, a subscriber connected somewhere else in Kenya can hold an address that every geolocation database reports as Mombasa.
