Summary
Proxsys
isp transit netherlands cable
PROXSYS-AS is operated by Proxsys B.V., a Dutch telecommunications provider based in Gorinchem.
What it's used for
- The address space carries infrastructure for regional water boards and security services, with netnames including
NL-WSHD-20181004(Waterschap Hollandse Delta),NL-WSRL-20181010(Waterschap Rivierenland),NVD-NET(NVD Beveiligingsgroep B.V.), andNL-WSBD-20201221(Waterschap Brabantse Delta). - The AS announces 4,608 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 100 observed neighbours; this ratio of modest address space against a high neighbour count indicates a transit or interconnection role rather than a large-scale access network.
- Traffic from this AS consists of corporate and municipal government data for water management authorities and security firms, as well as general internet services provided by Proxsys.
Notable
- Registrants for the largest prefixes include Proxsys B.V., Waterschap Hollandse Delta, Waterschap Rivierenland, NVD Beveiligingsgroep B.V., and Waterschap Brabantse Delta, indicating the space is subdivided among specific organizational clients rather than being a single monolithic block.
- The inventory consists of five distinct IPv4 prefixes ranging from /21 to /24, reflecting a fragmented address estate assigned to different end-users or departments.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 443 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.
