Summary
Deutsche Boerse
finance enterprise business
A stock exchange with 106 BGP neighbours, announcing one /19 as eight separate pieces.
What it's used for
- Trading and market-data connectivity. 8,192 addresses in eight IPv4 prefixes, one IPv6 prefix, and 106 observed BGP neighbours.
Notable
- All eight blocks carry the same netname,
DBAG, with contactsDeutsche Boerse AG NOS CCI Teamand a dedicated abuse role. - The announcements are
193.29.64.0/21,193.29.72.0/23,193.29.74.0/24,193.29.75.0/24,193.29.76.0/23,193.29.78.0/24,193.29.79.0/24and193.29.80.0/20. - Together they cover
193.29.64.0/19exactly, with nothing left over and nothing overlapping. - One sampled address of eighteen answered, as
billing-test.clearstream.com. - The IPv6 announcement is
2a00:7440::/32.
Interesting
- 106 neighbours for eight thousand addresses is the signature of an exchange rather than a network operator. Trading firms connect directly to the venue because every intermediate hop costs microseconds, so the exchange ends up peering with its own customers on a scale that would otherwise take a national carrier.
- Announcing a
/19as eight pieces when one route would carry the same traffic is usually history rather than design, but in a latency-sensitive network it can also be a way to steer particular customers down particular paths. Either way, all eight routes are carried by every router on the Internet. - The single reverse name belongs to a test billing host at the clearing subsidiary. Reverse DNS is public, so naming a system for its function and its environment hands a stranger a starting point for free.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
