About this network

TELEFIBER is the autonomous system for Telefiber AS, a regional broadband provider in Telemark, Norway.

What it's used for

• The address space carries residential and business broadband customers, evidenced by reverse DNS entries such as bb.cust.telefiber.no and bb.cust.hknett.no.
• The AS announces 31,744 IPv4 addresses across 15 prefixes and 3 IPv6 prefixes, while maintaining 15 observed neighbours, a ratio indicative of an access network rather than a transit provider.

Notable

• Registrants include Telefiber AS, Snogg Fiber AS, NC-Spectrum AS, Numedal Fiber AS, Notodden Kommune, and Bykle Breiband AS, reflecting a mix of owned and acquired or leased infrastructure.
• The address inventory is finely subdivided into multiple /22 and /21 blocks, consistent with site-by-site segmentation for a regional fiber operator.
• The presence of hknett.no in reverse DNS and Snogg Fiber AS as a registrant suggests historical consolidation of local fiber networks under the Telefiber brand.
