About this network

HSPEED-AS is operated by Die Netz-Werker Systemmanagement und Datennetze AG.

What it's used for

• The address space carries business and IT infrastructure traffic, evidenced by reverse DNS entries like web238-254.hspeed.net and web130-254.hspeed.net.
• With 3072 IPv4 addresses announced across 3 prefixes and 10 observed neighbours, the ratio suggests a regional business or IT services provider rather than a large-scale transit or residential access network.

Notable

• Registrants for two of the three announced prefixes (193.24.236.0/22 and 194.147.128.0/22) are explicitly listed as Die Netz-Werker, while the third (45.91.212.0/22) is registered to CeCon Computer Systems Handelsgesellschaft mbH.
• The operator is identified in secondary sources as a nationwide IT system house (IT-Systemhaus) based in Berlin, formerly associated with Insoft EDV-Systeme.
• The inventory consists of three /22 IPv4 blocks and a single /29 IPv6 prefix, indicating a modest, segmented address estate typical of a corporate or service provider environment.
