About this network

The AS handle FIBERING is held by Fiberwide S.p.a.

What it's used for

• The address space carries residential and business broadband traffic, evidenced by reverse DNS entries such as dsl-46.20.91.254.fibering.com and bc-46.20.87.255.fibering.com.
• The network announces 17,408 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, with 39 observed neighbours, indicating a role as an access provider rather than a transit carrier.
• Traffic from this AS consists of subscriber eyeballs for fixed-line internet access, including DSL and fiber connections, serving both consumer and business customers in Italy.

Notable

• Registrants for the majority of prefixes are consistent with the announcer, listing Fibering NOC Group, Fibering Admin Group, Fiberwide S.p.a., and Fibering Abuse.
• The operator was formerly known as Dialogic S.r.l. and rebranded to Fiberwide in 2016, consolidating its consumer brand Fibering into the B2B-focused Fiberwide identity.
• The address inventory includes a block registered to Telecontrol Vigilanza S.R.L. (185.95.136.0/22), which does not align with the primary Fibering/Fiberwide registrants.
