AS-BBT is operated by Blackburn Technologies II, LLC.

What it's used for

  • The address space carries prefixes with netnames BTIL-3 and BBN-PR-02, indicating infrastructure for Blackburn Technologies in Puerto Rico.
  • The AS announces 1280 IPv4 addresses and 25 IPv6 prefixes while maintaining 34 observed neighbours, a ratio that signals a transit or network service provider role rather than a large access network.

Notable

  • The operator is also known as Blackburn Networks and operates as a Network Service Provider (NSP) with global scope.
  • The inventory consists of three IPv4 prefixes and ten IPv6 prefixes, with the IPv6 space subdivided into multiple /40s and larger blocks under the 2604:98c0::/46 range.

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 1,775 prefixes, as published 2026-10-11. 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.
