Summary

SysUP IT GmbH & Co KG

Austria · AI-generated

business hosting austria

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-22. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
