Summary

nocyo GmbH

Germany · AI-generated

business it distribution germany

The AS handle NOCYO-AS is held by nocyo GmbH.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames DE-NOCYO-20100119 and nocyo-pi1 registered to nocyo Hostmaster; nocyo GmbH.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints for an IT hardware distributor, supporting office operations and web/API services for its distribution business.

Notable

  • All registrants for the announced prefixes agree with the announcer, consistently listing nocyo Hostmaster; nocyo GmbH.
  • The address inventory is compact and finely subdivided into three IPv4 blocks and one IPv6 block, consistent with an internal 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 1,771 prefixes, as published 2026-10-15. 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.
