Summary

sysops Finland Oy

Finland · AI-generated

business managed-services turku

SYSOPS-FINLAND is operated by sysops Finland Oy, a Finnish IT maintenance and expert services company based in Turku.

What it's used for

  • The address space is registered under the netname FI-SYSOPS-20120615 with registrant sysops Finland Oy, indicating a corporate allocation for the company's own infrastructure.
  • The AS announces a single IPv4 prefix, 5.83.56.0/21, comprising 2048 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small-scale corporate or managed services network rather than a transit provider or large-scale access network.
  • Traffic from this AS consists of corporate endpoints and managed service infrastructure for sysops Finland Oy's clients, supporting their IT maintenance and expert services operations.

Notable

  • The RDAP registrant sysops Finland Oy matches the AS holder, confirming consistent ownership of the address space.
  • The address inventory is compact, consisting of a single /21 block, which aligns with the company's role as a specialized IT services provider rather than a large-scale ISP.

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 1,781 prefixes, as published 2026-10-16. 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.
