What a Frauenfeld IP address tells you

Frauenfeld's routing record is one exchange and one building. CHIX-CH, registered as CHIXSWITZERLAND, has 69 participants, while Datacenter Thurgau holds 2 networks, so almost all of the local peering weight sits on the exchange rather than in colocation. None of Switzerland's mobile carriers are on that participant list. The ASNs of Swisscom, Sunrise and Salt from the carrier registry do not appear, so no mobile traffic is recorded as being exchanged in the city.

An address that geolocates here is unlikely to describe a device in Frauenfeld. Operators announce address blocks against a registry record holding one address for the entire company, and geolocation databases take that published location as the city. Swiss mobile traffic in particular leaves the network through a small set of gateways, so a whole pool of subscriber addresses can carry the same city string. A label of Frauenfeld says something about paperwork and routing policy, not about where a handset or a server is plugged in.

The origin ASN on the exact prefix is the more reliable field. It names the network that announces the block, and the netname beside it names the organisation that holds the range, both of which stay stable when a database changes its city guess. Checking those against the 69 participants of CHIX-CH shows whether the announcing network has any recorded presence in Frauenfeld at all, or whether the city string is inherited from a registry address somewhere else.

Questions

Which internet exchanges are in Frauenfeld?

One. PeeringDB registers CHIX-CH, listed in full as CHIXSWITZERLAND, in Frauenfeld with 69 participants. The city has a single colocation facility on record as well, Datacenter Thurgau, with 2 networks present.

Do Swiss mobile carriers peer in Frauenfeld?

Not according to this snapshot. The mobile ASNs of Swisscom (AS3303), Sunrise (AS6730 and AS5426) and Salt (AS15796) are absent from the CHIX-CH participant list, so no Swiss mobile carrier peering is recorded in the city.

Does an IP that geolocates to Frauenfeld mean the device is there?

No. The city label comes from the address an operator published with its block in a registry, and databases repeat it. Read the origin ASN and the netname on the specific prefix to learn which network announces the address.
