Summary
Tradeweb
enterprise legacy
TRADEWEB is Tradeweb, the electronic marketplace for fixed income, rates, credit, equities and money markets. Institutional clients — banks, asset managers, hedge funds — connect to its platform to price and execute trades; the sampled reverse DNS, pviewer-us.tradeweb.com, is one of its client-facing systems.
What it's used for
RIS observes 17 IPv4 prefixes carrying just 4,096 addresses, no IPv6, and 6 observed BGP neighbours. Seventeen prefixes to hold four thousand addresses means almost everything here is a /24 — the smallest globally routable unit.
That is the signature of a financial extranet rather than a hosting estate. The blocks come from visibly different parent ranges: 12.151.228.0/24 and friends out of AT&T space, 38.65.195.0/24 out of Cogent's, plus 64.237.108.0/22-worth of Tradeweb's own, and scattered /24s from several other carriers' historic allocations. A trading venue accumulates these by taking a small assignment from every carrier and every colocation site it needs a presence in, then announcing all of them from its own ASN so that clients reach the platform over whichever private circuit or exchange they already buy.
Notable
Address count is a bad proxy for importance here. Four thousand addresses is a rounding error next to a consumer ISP, but this AS fronts a venue that intermediates enormous daily notional volume. Latency, reachability and path diversity are what the network is optimised for; scale, in the eyeball sense, is irrelevant to it.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
