Summary

BitHawk AG

Switzerland · AI-generated

business enterprise switzerland

The AS handle BITHAWK is held by BitHawk AG.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname BITS and registrant NOC; BitHawk AG for the prefix 193.5.116.0/22.
  • The network announces 1024 IPv4 addresses across 1 prefix while maintaining 39 observed neighbours, a ratio indicative of a transit or peering-heavy role rather than a large access network.
  • Traffic from this AS consists of internal corporate communications, data center operations, and enterprise service delivery for BitHawk's IT services and Microsoft 365 governance projects.

Notable

  • The registrant NOC; BitHawk AG aligns with the AS holder, confirming consistent ownership of the announced space.
  • BitHawk AG was formerly known as Bison IT-Services AG, a rename that reflects its evolution into a broader digital transformation and IT services provider.
  • The inventory consists of a single contiguous /22 block, representing a compact and focused address estate for the organization's Swiss operations.

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 1,773 prefixes, as published 2026-10-13. 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.
