An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS30848 was assigned to IT-TWT-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS30848 currently announces 59 IPv4 block(s), totaling about 122.9 thousand addresses (122,880 in all), registered in Italy. Services from IT-TWT-AS are reached through these addresses.
What it means to see AS30848 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS30848. That means the other end sits on the IT-TWT-AS network (Italy). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
