Summary

Foreshore

Jersey · AI-generated

hosting isp business

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.

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: 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.
