Summary

Gemeente Leeuwarden

Netherlands · AI-generated

government municipal netherlands

ASGLWD1 is operated by Gemeente Leeuwarden, the municipal government of Leeuwarden in the Netherlands.

What it's used for

  • The address space carries municipal infrastructure, identified by the netname LEEUW-NET and registrant Gemeente Leeuwarden.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix and one IPv6 /48 prefix, with only 2 observed routing neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of municipal office workers, city services, and internal administrative endpoints for the city of Leeuwarden.

Notable

  • The RDAP registrant Gemeente Leeuwarden matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, typical of a municipal IT estate segmented for internal use.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
