About this ASN.

Updated  ·  Confidence: High  ·  6 sources  ·  How this page is checked

AS3269 carries the legacy "Interbusiness" name (ASN-IBSNAZ) and is the main consumer-facing access ASN for TIM, Italy's incumbent telecom operator, registered under RIPE to TIM S.p.A. (formerly Telecom Italia S.p.A.) in Rome. It serves residential ADSL/FTTH broadband plus mobile data and is one of the largest eyeball networks in Italy, announcing on the order of 341 prefixes (around 710 counting more-specifics, ~20.8 million addresses) with only minimal IPv6 origination. Its principal upstream is its own international/wholesale arm, Telecom Italia Sparkle (Seabone, AS6762), through which it reaches the wider Internet, and CAIDA places it at AS Rank #268 with a customer cone of 187 ASNs. For triage, an address here is typically an Italian home or mobile subscriber on dynamic, often CGNAT-shared addressing, so behavior should be attributed to subscriber sessions rather than to the operator. The TIM brand was unified in 2016, after which the group consolidated under the TIM identity; registry and CAIDA records still carry the legacy "Telecom Italia" org name, and the precise legal-name-change date is not cleanly sourced.
