About this network

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, 141.176.52.0/22 and 141.176.60.0/23.
• All three carry the netname ROTTERDAM and list the authority plus a role object named PoR-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.
