About this network

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.
