Summary

exaSys AG

Switzerland · AI-generated

business it-services cloud

The AS handle EXASYS is held by exaSys AG.

What it's used for

  • The address space carries IT services and cloud infrastructure, evidenced by the netname CH-EXASYS-20111108 and the registrant exaSys AG.
  • The AS announces 2048 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
  • Traffic from this AS consists of web and API endpoints for Swiss IT services and cloud clients, supporting the company's role as an independent IT services division.

Notable

  • The registrant exaSys AG matches the AS holder, confirming consistent ownership of the announced space.
  • exaSys AG was founded in 2009 as a subsidiary of HiHo AG to expand IT services as an independent division.
  • The inventory consists of a single IPv4 prefix (134.90.216.0/21) and one IPv6 prefix (2a03:d380::/32), representing a compact corporate estate.

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 1,784 prefixes, as published 2026-10-19. 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.
