Network type: residential

About this network

FUSE-NET is the internet-access autonomous system of Cincinnati Bell Telephone Company LLC, the incumbent telephone carrier for the Cincinnati region, now trading as altafiber. Fuse Internet Access is the ISP brand carried on this AS.

What it's used for

• Consumer and business broadband across greater Cincinnati and northern Kentucky, including the carrier's fibre-to-the-home footprint.
• Roughly 800k IPv4 addresses, one of the larger regional eyeball pools in the ARIN region and consistent with a legacy telco serving a metropolitan area.

Notable

• This is an eyeball network: the addresses here sit behind residential subscribers, so traffic is heavily inbound and diurnal. It is not a hosting or transit AS.
• ARIN's registration for the ASN dates to 1995, matching the period when incumbent telcos were standing up dial-up and early broadband arms.

Interesting

• Cincinnati Bell is one of the few US incumbent local exchange carriers that stayed independent through the Bell-system consolidations, which is why a single metro has its own telco AS at all.
