Unclassified ARIN Enterprise
Summary
Jane Street
finance enterprise infrastructure
Eleven blocks in three regions, a netname containing a date from 1992, and nothing published anywhere.
What it's used for
- A trading firm's network. 3,072 addresses across 11 IPv4 prefixes, with 13 observed BGP neighbours and no IPv6 announced.
Notable
- The blocks are registered in three regions:
JSCL-1and carrier-issued space in one, a country-prefixed carrier netname andUK-JANESTREET-19920228through a European provider, andJANE-HKwith an incident response contact in another. - One block is labelled with a carrier's name alongside the firm's, under that carrier's own incident response team.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Ten of the eleven announcements are a single
/24, the smallest block most of the internet will carry, and each sits in a different part of the address space. That is a firm putting one small presence next to each market it trades on, because the machine has to be in the building where the exchange is. - One netname ends in a date from long before the company existed. That block was assigned to somebody else in the early nineties, changed hands, and kept the label with the original allocation date frozen into it.
- Contacts registered as incident response teams rather than individuals are a requirement in some regions and a good idea in all of them. The record is built to survive staff turnover.
- Thirteen neighbours against three thousand addresses is the ratio that gives the game away: connectivity matters far more here than address count. Nothing is published in reverse DNS because nothing here is meant to be found.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
