Network type: residential

AS12042 announces 78 IPv4 prefixes covering 147,200 addresses and 2 IPv6 prefixes.

About this network

A Minnesota-rooted regional telephone network now part of Consolidated Communications, whose consumer fiber brand is Fidium.

What it's used for

• Residential and business broadband across a rural and small-city footprint in the upper Midwest, spanning legacy DSL and newer fiber.

Notable

• The registry records a corporate lineage rather than a single company. Blocks are held under HickoryTech Corporation, the ENVENTIS and CONSO netnames, and Fidium — the Mankato, Minnesota telco that became Enventis, was bought by Consolidated in 2014, and now sells fiber under the Fidium name.
• Reverse DNS preserves the same history in parallel: sampled addresses answer under hickorytech.net, cpinternet.com and cptelecom.net, three brands that predate the current one.
• One group of prefixes is registered to IdeaOne Telecom, a Fargo, North Dakota operator absorbed into the same group.

Interesting

• 123 prefixes for 147,000 addresses. Rollups of independent rural telcos always look like this — the fragmentation is a record of how many separate companies were bought.
