Leeds · United Kingdom
PeeringDB records no internet exchange in Leeds and six colocation facilities holding 38 network presences. Three aql buildings carry 34 of them, with aql DC2 the busiest at 22 networks. A Leeds IP address tells you what an operator wrote in a registry record, not where the device using it sits.

What a Leeds IP address tells you
Leeds appears in the registry as colocation and nothing else. The city has no exchange fabric, so there is no participant list to compare, and the 38 network presences PeeringDB counts sit across six buildings. aql accounts for 34 of them through DC2 with 22 networks, DC5 with seven and DC3 with five. Templus DC Leeds LEE01 holds two, and Leeds DC1 and DC14-Leeds hold one each. With no exchange in the city, none of the UK mobile ASNs, EE's AS2856 and AS12576, O2's AS29180 and Vodafone's AS25135, has a Leeds peering entry.
An address that geolocates to Leeds need not be a device in Leeds. An operator announces an address block from one registry record naming one place, and the same block can cover equipment or subscribers over a wide area. Mobile traffic concentrates through a small number of gateways, so one published location stands in for everybody behind them. Geolocation databases read what the operator published, which makes the city field a statement about paperwork rather than about position.
Checking the origin ASN and the netname on the covering prefix answers more than the city does. A prefix announced by AS2856, AS12576, AS29180 or AS25135 belongs to a UK mobile network wherever a lookup places it, and a prefix registered to a network with racks in aql DC2 is a hosted address in a known building. The route object names the announcing network, and it stays fixed while city labels vary from vendor to vendor.

Questions
Which internet exchanges are in Leeds?
PeeringDB records none. Leeds is present in the registry through colocation, with six facilities holding 38 network presences, of which three aql sites account for 34. Without an exchange record the city has no participant counts to read.
Do UK mobile carriers peer in Leeds?
No Leeds exchange appears in PeeringDB, so there is no peering record for any of them in the city. The carrier registry gives the UK mobile ASNs as AS2856 and AS12576 for EE, AS29180 for O2 and AS25135 for Vodafone.
Does an IP that geolocates to Leeds mean the device is there?
No. The city attached to an address comes from the block's registry entry and the operator's published location. Mobile blocks route through a few gateways and can carry subscribers anywhere in the country while every address reads as Leeds.
