Unclassified RIPE
Summary
Paradigm
government infrastructure enterprise
The AS handle is a street address, written in two languages at once.
What it's used for
- A regional public sector information technology centre. One IPv4
/19and two IPv6 prefixes announced from Belgium, eight thousand addresses, through two observed BGP neighbours.
Notable
- The handle field holds a postal address rather than a name: one street, given in both of the region's official languages joined by a hyphen, followed by a building number.
- The netname pairs the country code with a four letter abbreviation and its equivalent in the other language, then a six digit date.
- The registrant field names that bilingual abbreviation as a technical contact and the organisation's current single word name separately, so the record spans a rebranding.
- Three addresses were queried for reverse DNS and none returned a name.
- Two IPv6 prefixes against one IPv4 block.
Interesting
- Officially bilingual administration shows up in the smallest places. Two of the three identifiers here carry both languages, because using one alone is a political choice.
- A street address in a name field is the most literal answer to where a network is that a registry ever gives. It is also the one field nobody will think to check.
- Announcing more IPv6 than IPv4 is the right shape for a public body building for the next decade rather than the last one.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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 1,784 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.
