Summary

Island Palms Hotel & Marina

United States of America · AI-generated

hosting business isp

The handle says what the network is for in plain words: guest internet.

What it's used for

  • A hotel's guest network. One IPv4 prefix announced from the United States, no IPv6, five hundred and twelve addresses, through one observed BGP neighbour.

Notable

  • The AS handle is three parts: the property's name run together, then the word for a guest, then the word for the network everyone is connecting to. It is one of the few handles here that states a purpose rather than an owner.
  • The netname keeps only the property's name and drops the purpose entirely, so the field with more room says less.
  • The holder is a hotel and marina, ampersand included, and the registrant repeats it exactly.
  • The block is small, contiguous, behind one observed neighbour, and it is the whole holding.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • A hotel running its own autonomous system for guest traffic is separating the people passing through from everything else the property runs. Guests do things that get addresses complained about, and keeping them in their own space keeps the reputation problem contained.
  • Five hundred addresses is roughly a room count with room to spare, which is what makes this allocation legible: the size was chosen against a building rather than against a forecast.
  • Naming a network after its purpose ages better than naming it after its owner. Properties change hands; guest internet stays guest internet.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
