Unclassified ARIN
Summary
Optus Customer Network
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.
