What a Milan IP address tells you
Milan carries 550 unique peers across four exchanges. MIX-IT holds 398 participants, more than the other three combined: MINAP Milan has 114, Equinix Internet Exchange Milan 35, and MegaIX Milan 3. Capacity also sits in colocation, where PeeringDB counts 590 network presences across 18 facilities. MIX DC CALDERA lists 267 networks and Retelit Avalon 1 lists 137, with Seeweb Milano Caldera at 59 and Equinix ML2 at 43. Two of Italy's three mobile operators show in MIX-IT's carrier records. WindTre brings AS1267 and AS24608, and Vodafone brings AS30722.
An address that geolocates to Milan may not be a device in Milan. An operator announces address blocks from a registry record, and that record carries one location for the whole allocation. Mobile addressing widens the gap, because a national carrier hands subscribers addresses from pools that leave the network through a small number of gateways, so a phone anywhere in Italy can appear on a block registered to Milan. Geolocation databases repeat whatever location the operator publishes, and they update when the operator updates it.
Someone checking an address should read the origin ASN and the netname on the specific prefix rather than the city label. AS16232 and AS30722 mark mobile access networks, as do WindTre's AS1267 and AS24608. An ASN belonging to a network racked in MIX DC CALDERA or Retelit Avalon 1 means something different, even when both addresses resolve to Milan. The prefix registration also shows whether the block is a nationwide operator pool or an assignment to one customer site.
Mobile carriers in Italy
A mobile address in Milan is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Milan?
PeeringDB lists four. MIX-IT, the Milan Internet eXchange, has 398 participants; MINAP Milan, the Milan Neutral Access Point, has 114; Equinix Internet Exchange Milan has 35; and MegaIX Milan has 3. Across all four the city records 550 unique peers.
Do Italian mobile carriers peer in Milan?
WindTre's AS1267 and AS24608 and Vodafone's AS30722 appear in MIX-IT's carrier records. PeeringDB does not list TIM's mobile AS16232 at any Milan exchange, which says nothing about private interconnection, since the registry only covers peering that members choose to publish.
Does an IP that geolocates to Milan mean the device is there?
No. The city label comes from the operator's own registry entry for the address block, and mobile pools are announced across a whole country. Read the origin ASN and the netname on the prefix to see which network holds the range and how it describes it.
