Summary

Optus Customer Network

Australia · AI-generated

enterprise legacy

An Australian customer network carried by Optus (TXU-AS-AP), registered with

APNIC under SingTel Optus with Melbourne contact details and an

abuse@optus.com.au contact.

What it's used for

  • A customer-operated network sitting behind Optus, one of Australia's largest telecommunications carriers.
  • The address space is a small enterprise-sized block rather than a consumer broadband pool.

Notable

  • The registry handle (TXU-AS-AP) and the holder name do not match: the handle survives from the customer the number was originally assigned to, while the current record is maintained under Optus. Handles routinely outlive the organisation that first used them.
  • Optus itself operates much larger and better-known ASNs; this one is a customer allocation, not an Optus backbone AS.
