About this network

InternetONE is the network of Internet One SRL, an Italian service provider based in Varese, Lombardy, which markets AS5398 as its "worldwide backbone".

What it's used for

• Fibre and wireless connectivity, VoIP telephony, cloud and managed hosting services for Italian business customers.
• IP transit and peering: the ASN is present at Italian and European exchanges and carries both the provider's own hosted services and its downstream customers.

Notable

• A provider-style ASN rather than an enterprise one: address space is split between access customers and hosted/cloud infrastructure, so geolocation of its ranges tends to cluster around northern Italy.
• The aut-num object states that AS5398 validates RPKI and rejects invalid prefixes from peers and customers, and that it applies route-flap damping.

Interesting

• Peering policy is selective, with technical details published through PeeringDB rather than in the RIPE object itself.
