Zaventem · Belgium

Zaventem has no exchange in PeeringDB, so its recorded connectivity sits entirely in colocation. Five facilities hold 50 network presences, with brusselsdc at 15, Digital Realty BRU3 at 14, Unix-Solutions DC Zaventem at 13, Digital Realty BRU4 at 6 and EXA Edge DC Zaventem at 2. Those are modest counts next to the 182 presences the registry records in Brussels, and no Belgian mobile operator appears in the carrier registry, so the data shows no mobile network peering in the town. Networks here reach each other over private links and through exchanges recorded elsewhere.

An address that geolocates to Zaventem may belong to a device anywhere on the announcing network. An operator registers an address block once, with one postal address, and that address can be an office or a national contact point rather than the place a subscriber sits. Mobile networks make the distance larger still, because traffic from across the country leaves through a handful of gateways and inherits whichever block those gateways announce. Geolocation providers copy the operator's published location, so a town-level answer can be an administrative artefact.

Check the routing record rather than the town name. The origin ASN identifies the network announcing the prefix, and the netname on that prefix shows how its holder describes the range and how wide the announcement is. Where an operator announces one block for a whole country, no city or town inside it means much on its own. The 50 network presences PeeringDB records across the five Zaventem facilities are the operators with equipment in the town, which is a much shorter list than the addresses geolocating to it.
