About this network

TERACOM-AB is operated by Teracom AB, a Swedish state-owned company providing communication services to operators of essential functions.

What it's used for

• The address space carries infrastructure for critical national functions, as indicated by the netname SE-SRUKAL on 193.235.2.0/24 and the generic net-185-153- blocks.
• With 1024 IPv4 addresses across 3 prefixes and 21 observed neighbours, the ratio suggests a specialized access or internal corporate estate rather than a large-scale consumer ISP or pure transit provider.
• Traffic from this AS consists of secure communications, VoIP, and data services for Swedish government agencies, military, and other essential public services that require resilience against natural disasters and cyber threats.

Notable

• Registrants for all announced prefixes consistently identify Teracom AB, Teracom RIPE Admin, and Teracom Technical Staff, aligning perfectly with the AS holder.
• Teracom originated from the spin-off of the state radio and TV broadcast network in 1993, later evolving into a dedicated provider for critical infrastructure.
• The inventory is small and finely subdivided into three distinct /24 and /23 blocks, reflecting a segmented internal corporate estate rather than a broad retail footprint.
