Autonomous systems

Holder names and prefix counts come from the RIPE NCC's RIPEstat Data API, fetched on 2026-09-06. Role and confidence come from the evidence linked in each row; "confirmed" means a PeeringDB or RIPEstat record, or the operator's own site, names the operator.

Mobile network codes

The MCC identifies the country and the MNC identifies the operator inside it. Together they appear in the IMSI of every SIM on the network and in device diagnostics; they are how a handset knows which network it is on.

About WindTre

WindTre is a mobile operator in Italy and part of CK Hutchison Holdings. The registry records two ASNs registered to WIND TRE S.p.A., AS1267 and AS24608, both documented as mobile and inherited from the former Wind and 3 Italia networks. WindTre uses MCC 222 with MNC 88, MNC 99 and MNC 37.

The registry records two ASNs for WindTre, both registered to WIND TRE S.p.A. and both documented as mobile. AS1267 comes from the ex-Wind network and announced 223 IPv4 prefixes and 2 IPv6 prefixes at the last probe. AS24608 comes from the former 3 Italia network and announced 16 IPv4 prefixes and no IPv6 prefixes. PeeringDB records AS24608 under the name H3G S.p.A., also known as TRE, as a network service provider, while no PeeringDB name is recorded against AS1267 at the last probe.

An address whose origin ASN is AS1267 or AS24608 is routed by WindTre. Both carry the mobile role in the registry, so an Italian address in either has a reasonable claim to being a mobile connection, but neither source separates consumer mobile traffic from fixed and enterprise traffic on the same numbers. The two ASNs also come from two networks that were merged, so a WindTre subscriber can appear under either one. The origin ASN identifies the operator, not the type of connection behind the address.

Research note. AS1267: PeeringDB net id 2174 name 'WINDTRE', website windtre.it, NSP, 50-100Gbps, scope Europe; RIPEstat holder 'ASN-WINDTRE WIND TRE S.P.A.', announced=true (ex-Wind network). AS24608: PeeringDB net id 3533 name 'H3G S.p.A.', aka 'TRE', website tre.it (former 3 Italia mobile network); RIPEstat holder 'WINDTRE-AS WIND TRE S.P.A.', announced=true. Both ASNs belong to WIND TRE S.p.A.; which one carries today's consumer mobile traffic vs. fixed is not separated by either source.

Questions

What is WindTre's ASN?
The registry records two confirmed ASNs for WIND TRE S.p.A., AS1267 and AS24608. AS1267 comes from the former Wind network and AS24608 from the former 3 Italia network. Both are announced and both are documented as carrying mobile traffic.
What is the MCC/MNC of WindTre?
WindTre uses MCC 222, the country code for Italy, with MNC 88, MNC 99 and MNC 37, written as 222-88, 222-99 and 222-37. The 222-88 row comes from the former Wind network and 222-99 from the former 3 Italia; 222-37 is listed with an unknown status.
Is an IP from AS1267 a mobile IP?
It can be. AS1267 is registered to WIND TRE S.p.A. and the registry documents it as mobile, but the same ASN also routes the operator's fixed and enterprise customers, and no source in the registry separates them. The ASN tells you the operator, not whether the address is a handset.

Where WindTre meets other networks

PeeringDB records WindTre as a participant at internet exchanges in 7 cities. Each city page lists the exchanges there and the other networks present.

Network cities in Italy: Milan, Rome, Turin, Padova, Palermo.

Sources

ASN and prefix data describe how the operator's networks are registered and announced. They do not identify an individual subscriber or where a device is, since carriers route traffic from many areas through shared gateways.
