Summary

Gemeente Schiedam

Netherlands · AI-generated

government municipal netherlands

GEM-SCHIEDAM is operated by Gemeente Schiedam, the municipal government of Schiedam in the Netherlands.

What it's used for

  • The address space carries municipal network infrastructure, identified by the netname MVS-RBD and registrant Gemeente Schiedam.
  • The AS announces a single IPv4 prefix, 194.26.120.0/21, comprising 2048 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour, the network functions as an isolated internal estate for municipal operations rather than a transit or access provider.

Notable

  • The RDAP registrant Gemeente Schiedam matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /21 block, indicating a consolidated internal network allocation for the municipality.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
