Summary

Belgium · AI-generated

government employment flemish public

VDAB is the autonomous system for Vlaamse Dienst voor Arbeidsbemiddeling en Beroepsopleiding (VDAB).

What it's used for

  • The address space carries internal government operations, with all six prefixes registered under the netname VDABNET and registrant Vlaamse Dienst voor Arbeidsbemiddelling en Beroepsopleiding.
  • The AS announces 3328 IPv4 addresses across 6 prefixes, all located in Belgium, while maintaining only 2 observed routing neighbours.
  • As the public employment service of Flanders, this network supports the digital infrastructure for job placement, vocational training, and administrative services connecting job seekers and employers.

Notable

  • All registrants in the RDAP data align perfectly with the AS holder, consistently listing Vlaamse Dienst voor Arbeidsbemiddelling en Beroepsopleiding as the registrant for every announced prefix.
  • The address inventory consists of six distinct IPv4 blocks within the 193.53.207.0/24 to 193.53.238.0/24 range, reflecting a segmented internal corporate estate typical of a large public institution.

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.
