About this network

AS-SOFTPLUS is operated by Datasource AG.

What it's used for

• The address space carries residential and business internet access, evidenced by netnames such as CH-DATASOURCE and CH-SCIT-20141124, and reverse DNS entries like egw126.tyle.ch.
• The AS announces 18,432 IPv4 addresses across 25 prefixes and 8 IPv6 prefixes, while maintaining 52 observed neighbours. This ratio of moderate address space to a high number of peering partners indicates a regional access provider with significant transit and peering requirements.
• As a cable and DSL ISP in Switzerland, the traffic consists primarily of subscriber eyeballs, including web browsing, streaming, and VoIP services for residential and small business customers.

Notable

• Registrants largely align with the announcer, with most prefixes registered to Datasource AG, though some blocks are registered to ScIT Informatik GmbH and Ralph Kraemer.
• The address inventory is fragmented into numerous /22 and /24 blocks, reflecting organic growth and acquisition of smaller ranges over time rather than a single large allocation.
