Summary

Gemeente Amsterdam

Netherlands · AI-generated

government municipal netherlands

GEMEENTE-AMSTERDAM is operated by Gemeente Amsterdam, the municipal government of Amsterdam.

What it's used for

  • The address space carries municipal IT infrastructure, as indicated by netnames NL-DIRECTIE-DDV-20101014 and NL-DIENST-ICT-20101014 registered to Gemeente Amsterdam.
  • The AS announces 3,584 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal municipal services, administrative endpoints, and city infrastructure systems managed by the city's IT department.

Notable

  • All registrants match the announcer, with Gemeente Amsterdam listed for all four IPv4 prefixes.
  • The address inventory is finely subdivided into small blocks, consistent with an internal corporate estate segmented by department or site.

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 1,773 prefixes, as published 2026-10-13. 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.
