About this network

FOUREDGE-AS is operated by Fouredge AB, a Stockholm-based IT outsourcing and infrastructure services provider.

What it's used for

• The address space carries corporate and client infrastructure, evidenced by the netname SE-AHLENS for the 193.235.154.0/24 block, which is registered to Ahlens AB, a Swedish retail company.
• The AS announces 4352 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 26 observed neighbours; this ratio of modest address space against a significant number of peering partners indicates a business network with substantial external connectivity rather than a large-scale access provider.
• Traffic from this AS consists of web and API endpoints, office workers, and IT operations infrastructure for Fouredge’s clients, including retail and enterprise entities.

Notable

• Registrants align with the announcer for the primary block, with SE-FE-DEN-20080909 registered to Fouredge AB, while the secondary block SE-AHLENS is registered to Ahlens AB, indicating a specific client or partnership arrangement.
• The inventory is split between a /20 block owned by Fouredge and a /24 block associated with Ahlens, reflecting a mixed corporate and client-hosted address estate.
