What a Lupfig IP address tells you
Lupfig's entry rests on a single building. Green Datacenter ZRH1, recorded under its former name Green Lupfig, holds 23 networks, and SBIX Zurich, the Securebit Internet Exchange Zurich, has 39 participants, which is the city's whole peering count. Exchange and facility are close in size here, so neither dominates the local record. No mobile carrier ASN from the Swiss registry is on the SBIX Zurich participant list, so Swisscom, Sunrise and Salt exchange their traffic elsewhere as far as PeeringDB shows.
The exchange name illustrates why a city label travels badly. SBIX Zurich is registered in Lupfig while carrying Zurich in its name, and operators do the same thing with address blocks, publishing one company location in a registry record that then stands for every prefix they announce. Geolocation databases read that published location. Mobile traffic compounds it, because a network routes its subscribers out through a few gateways and a single city string ends up covering addresses used across the country.
Someone checking an address labelled Lupfig should read the origin ASN and the netname on the prefix containing it. Those two fields name the announcing network and the organisation holding the range, and they do not change when a database revises its city guess. If the origin belongs to a network with equipment in Green Datacenter ZRH1 or a seat on SBIX Zurich, the label has something behind it. If not, the city string came from a registry address somewhere else.

Questions
Which internet exchanges are in Lupfig?
One. PeeringDB registers SBIX Zurich, the Securebit Internet Exchange Zurich, in Lupfig with 39 participants. The city also has one colocation facility on record, Green Datacenter ZRH1, formerly Green Lupfig, with 23 networks present.
Do Swiss mobile carriers peer in Lupfig?
No mobile carrier ASN appears in this snapshot. Swisscom (AS3303), Sunrise (AS6730 and AS5426) and Salt (AS15796) are absent from the SBIX Zurich participant list, so the registry records no Swiss mobile peering in the city.
Does an IP that geolocates to Lupfig mean the device is there?
No. A city label reflects the location an operator published for its address block, which can be an office rather than the equipment. Check the origin ASN and the netname on the exact prefix to see which network announces it.
