AS7543 PRNSI-AS-AP - PT Reach Network Services Indonesia
Unclassified APNIC
Summary
PT Reach Network Services Indonesia (Telstra International)
enterprise legacy
PRNSI-AS-AP is PT Reach Network Services Indonesia, the Jakarta-registered arm of Telstra International. Every prefix it announces resolves under telstraglobal.net, and the address blocks inside it are registered to Telstra International contacts in Hong Kong.
What it's used for
- Business connectivity in Indonesia delivered on Telstra's international backbone: IP transit and enterprise access for corporate customers in and around Jakarta.
- The reverse DNS is Telstra's global customer-link naming, with names such as
NNNNN.jakt05.cu.telstraglobal.netmarking Jakarta customer aggregation routers.
Notable
- This is a business/enterprise network, not a consumer ISP. The address space is small, and what is there is handed out as customer assignments off Telstra's network rather than as any subscriber pool. There are no residential-looking reverse-DNS patterns anywhere in it.
- The holder name is the honest one here, but it is easy to misread: "Reach Network Services" reads like an independent Indonesian ISP when the operator is really a local licensed entity of a large Australian carrier.
Interesting
- The Reach name is a fossil. Reach was the international-carrier joint venture Telstra and PCCW formed in 2001, pooling their subsea cables, gateways and satellite capacity. The joint venture is long gone from Telstra's branding, but the Indonesian company and this AS still carry the name.

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 2026-11-12. 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.
