Edinburgh · United Kingdom
PeeringDB records no internet exchange in Edinburgh and three colocation facilities holding 40 network presences, all of them Pulsant sites. Pulsant Edinburgh SC-1 at South Gyle carries 37 of the 40. An Edinburgh IP address reflects an address block's registry record and the operator's published location rather than a device's position.
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 |
|---|---|---|
| Pulsant Edinburgh SC-1 (South Gyle) | 37 | The Clocktower Estate, Flassches Yard South Gyle Crescent |
| Pulsant Edinburgh SC-3 (Newbridge) | 2 | 7 Claylands Road Newbridge |

What a Edinburgh IP address tells you
Edinburgh's entry in the registry is small and concentrated. PeeringDB lists no internet exchange in the city, so there is no participant count to read, and all 40 network presences sit in three Pulsant buildings. South Gyle, recorded as Pulsant Edinburgh SC-1, holds 37 of them, with Newbridge on two and Medway on one. None of the UK mobile ASNs in the carrier registry, EE's AS2856 and AS12576, O2's AS29180 and Vodafone's AS25135, has a peering record here, because the city has no fabric for one.
An address that geolocates to Edinburgh can sit anywhere the announcing network reaches. Operators register an address block once, against a single location, and traffic from that block originates wherever the network carries it. Mobile traffic from Scottish subscribers leaves through gateways that need not be in Scotland, and the addresses on those gateways carry the location the operator published for them. Geolocation databases repeat that published value, so the city on the record and the city of the device stay separate facts.
The origin ASN and the netname on the specific prefix carry more information than the city field does. A prefix announced by AS2856, AS12576, AS29180 or AS25135 is a UK mobile block whatever town a lookup prints for it. A prefix registered to a hosting network with racks at Pulsant South Gyle is a fixed address in a building. Both can return Edinburgh to the same query, and the ASN is what separates them.

Questions
Which internet exchanges are in Edinburgh?
None appear in PeeringDB. The city is recorded through colocation alone, with three Pulsant facilities holding 40 network presences between them and Pulsant Edinburgh SC-1 at South Gyle accounting for 37. There are no participant lists to read for the city.
Do UK mobile carriers peer in Edinburgh?
The registry has no Edinburgh exchange for them to appear at, so there is nothing to show. EE holds AS2856 and AS12576 in the UK carrier registry, O2 holds AS29180 and Vodafone holds AS25135, and none of them has an Edinburgh peering entry.
Does an IP that geolocates to Edinburgh mean the device is there?
No. The city on an address comes from the registry record for the block and from the operator's own published location. A mobile block can serve subscribers across the United Kingdom while every lookup against it returns the same Scottish city.
