Summary

Butterfly Research

Cayman Islands · AI-generated

enterprise legacy

A small network registered to Butterfly Research (BR), with an ARIN registrant address in George Town, Grand Cayman.

What it's used for

  • Announcing a handful of small IPv4 blocks; very little about the network is publicly documented, and the announced space carries only a small number of hosts.

Notable

  • ARIN's record for this ASN dates from December 2024, so the number appears to have been reissued to its current holder. Despite sitting low in the ASN space, it should not be read as an early-internet allocation.
  • The address footprint is tiny and the network has minimal peering — this is an end-user or single-purpose network, not a provider.

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: 431 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.
