Unclassified RIPE
Summary
Port of Rotterdam
infrastructure enterprise business
A seaport authority with its own autonomous system and a netname that is just the city.
What it's used for
- The network of the port authority of Rotterdam. 1,792 addresses across three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- The AS handle is
POR-NET Port of Rotterdam network. - The prefixes are
141.176.38.0/24,141.176.52.0/22and141.176.60.0/23. - All three carry the netname
ROTTERDAMand list the authority plus a role object namedPoR-NET abuse handling.
Interesting
- Almost every netname in this range is a company, an abbreviation or a dated code. This one is a city. It reads like a label written when the allocation was thought of as belonging to a place rather than to an organisation, which is how a lot of early space was described.
- Three separate announcements from scattered positions inside one legacy /16 mean the port received its space in pieces from a larger holder's range, and the gaps between them belong to someone else. The routing table has to carry all three because they cannot be summarised into one.
- Port authorities run industrial control, traffic management and tenant services, which is a wider job than an office network and explains why one exists here at all.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
