business financial trading australia

The AS handle TRADEWEB-AS-AP is held by Tradeweb Australia Pty Ltd.

What it's used for

  • The address space carries infrastructure for a financial trading platform, evidenced by reverse DNS entries such as yb64.yieldbroker.com and netnames TRADEWEB-AU.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a business network rather than a transit or access provider.
  • Traffic from this AS consists of electronic trading platform endpoints and API services for government bonds and interest rate derivatives.

Notable

  • Registrants for both announced prefixes are Tradeweb Australia Pty Ltd, matching the AS holder.
  • The operator formerly operated as Yieldbroker, which now operates as Tradeweb Australia Pty Ltd.
  • The inventory consists of two /24 blocks, 103.232.31.0/24 and 202.74.32.0/24, with no IPv6 prefixes announced.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
