About this network

SYSUP- is operated by SysUP IT GmbH & Co KG.

What it's used for

• The address space carries infrastructure for SysUP IT, with reverse DNS entries pointing to rz01.sysup.at (e.g., 77-75-17-0.rz01.sysup.at) and brunold.net (e.g., 195-43-139-64.brunold.net).
• The AS announces 3072 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale business or internal corporate network rather than a transit provider.
• Traffic from this AS consists of web and API endpoints for SysUP IT's services, as indicated by the sysup.at domain in the reverse DNS records.

Notable

• Registrants for the majority of prefixes (AT-SYSUP-20070502, AT-SYSUP-20160921) are SysUP IT GmbH & Co KG, while the prefix 195.43.139.0/24 is registered to Max Brunold under the netname STAGETWO.
• The address inventory is finely subdivided into five distinct IPv4 prefixes, suggesting site-by-site segmentation or separate service allocations within the corporate estate.
