About this network

The netname names the island twice, once as a country code and once in words.

What it's used for

• A hosting and connectivity provider in Jersey. 8,448 addresses across thirteen IPv4 prefixes, one IPv6 prefix, and one observed BGP neighbour.

Notable

• Eleven blocks share the netname JE-FORESHORE-JERSEY-20000406; one is JE-FORESHORE-JERSEY-20140918.
• 185.70.158.0/24 is SURE-IOM-BB, registered to a different party.
• Twelve of the prefixes are pieces of the contiguous range starting at 213.167.64.0.
• One of eighteen sampled addresses returned a name: stomp-dr.access.foreshore.net.

Interesting

• JE and JERSEY in one netname is redundancy nobody removed, and it is genuinely useful: the two-letter code is unreadable to most people, the word is unambiguous, and the field is free text so both fit.
• A block registered to another operator, whose name points at a different island, is announced from here. Small jurisdictions have few providers and they interconnect closely, so space crossing between them is routine rather than suspicious.
• The one reverse name that answered carries a service name and a two-letter suffix, the kind of shorthand that means something specific to the operator and nothing to anyone else.
• Thirteen prefixes behind a single neighbour is fine-grained internal steering with only one way out, which makes the split visible to the whole internet for no external benefit.
