Summary

DIVD

Netherlands · AI-generated

security nonprofit research netherlands

The AS handle DIVD is held by Stichting Dutch Institute for Vulnerability Disclosure.

What it's used for

  • The address space carries infrastructure for a Dutch non-profit focused on vulnerability disclosure and internet security, as indicated by the netname NL-DIVD-20210413 and the registrant identity.
  • The AS announces a single IPv4 prefix, 194.5.73.0/24, comprising 256 addresses, with no IPv6 prefixes in inventory.
  • With only 1 observed neighbour, the network operates as a small, self-contained endpoint rather than a transit or access provider, consistent with an internal corporate or organizational estate.

Notable

  • The RDAP registrant for the announced prefix matches the AS holder, Stichting Dutch Institute for Vulnerability Disclosure.
  • The address inventory is minimal, consisting of a single /24 block, which aligns with the organization's role as a specialized security institute rather than a large-scale service provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,771 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.
