Summary

Bloomberg

United States · AI-generated

enterprise finance legacy

BLOOMBERG is registered to Bloomberg Financial Markets Limited Partnership, the entity behind Bloomberg L.P. — the financial data, news and Bloomberg Terminal company. The ASN dates to a 1997 ARIN registration.

What it's used for

  • Bloomberg's own corporate and market-data infrastructure. This is a small secondary AS: it announces just two /24s, carved out of Bloomberg's own large legacy 69.184.0.0/13 allocation. Bloomberg's main traffic rides other Autonomous Systems.
  • The two prefixes carry no public reverse DNS, consistent with internal or restricted-access infrastructure rather than public-facing services.

Notable

  • An IP here is Bloomberg itself — its network, its terminals, its services — not a hosting tenant or a consumer. Treat it as enterprise financial-sector address space.
  • Because the AS announces so little, size gives no sense of Bloomberg's actual network footprint. Address count measures what is announced from this ASN, not what the company runs.

Interesting

  • The ARIN records still carry Internic-Technical role contacts, a leftover of the InterNIC era when the registration was made.

Reputation

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
