Summary
SIDN
registry anycast dns netherlands
SIDN-ANYCAST is operated by Stichting Internet Domeinregistratie Nederland (SIDN).
What it's used for
- The address space carries SIDN's anycast DNS infrastructure, as indicated by the netnames
SIDN-ANYCAST1andSIDN-ANYCAST4and the AS handle. - The AS announces 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, indicating a small, focused anycast service rather than a transit or access network.
- Traffic from this AS consists of DNS queries and responses for the .nl top-level domain, supporting the registry's role in managing Dutch domain names.
Notable
- Registrants for both announced prefixes are listed as Stichting Internet Domeinregistratie Nederland, matching the AS holder.
- SIDN was established in 1996 to take over .nl domain registration from Centrum Wiskunde & Informatica (CWI) as the number of .nl domains grew.
- The inventory consists of two /24 IPv4 blocks and two /48 IPv6 blocks, a compact allocation typical for a dedicated anycast service.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
