What a Slough IP address tells you
Slough's weight sits in colocation rather than in peering. PeeringDB records no internet exchange in the city and 439 network presences across 20 facilities. Equinix LD5 holds 163 of them, LD4 80, LD7 76 and LD6 75, so four buildings under one operator carry 394 of the 439. Iron Mountain's London LON-1 has seven networks and VIRTUS LONDON4 six, and a facility named SloughIX is listed with one. With no exchange fabric recorded here, none of the UK mobile ASNs, EE's AS2856 and AS12576, O2's AS29180 and Vodafone's AS25135, has a Slough peering entry.
Several of these buildings carry London in their registry names, which is a clue about how addresses here get labelled. An operator with racks in Slough can register the address block against a London location, and geolocation databases take the operator's published value as given. Mobile addresses behave the same way on a wider scale, since subscriber traffic exits through a few gateways and inherits whatever location those gateway blocks carry. A Slough answer and a London answer can describe the same rack.
Reading the origin ASN and the netname on the covering prefix beats reading the city. An address from a hosting or transit network with racks in one of the Equinix Slough buildings looks nothing like an address originating from AS2856, AS12576, AS29180 or AS25135, the mobile ASNs the UK carrier registry lists. The prefix's route object names the network announcing it, and that answer does not shift between one geolocation vendor and the next.

Questions
Which internet exchanges are in Slough?
None that PeeringDB records. The city's presence in the registry is colocation, with 20 facilities holding 439 network presences, of which Equinix LD5, LD4, LD7 and LD6 account for 394. A facility named SloughIX appears with a single network attached to it.
Why do Slough data centres carry London in their names?
The registry names five Equinix sites here in the form 'Equinix LD5 - London, Slough', pairing both places in one entry. Address records registered from these buildings can carry either name, which is one reason a lookup may print London for a rack in Slough.
Does an IP that geolocates to Slough mean the device is there?
No. Nothing in the registry measures a device. The city on a block is what the operator wrote in its record, and mobile blocks in particular carry subscribers well beyond any single town while returning one location.
