Unclassified ARIN
Summary
PT Telkom Satelit Indonesia (Telkomsat)
TELKOMSAT-AP is PT Telkom Satelit Indonesia, the satellite subsidiary of state-owned PT Telkom Indonesia. Telkomsat operates the Telkom satellite fleet and sells transponder capacity, VSAT service and satellite-backed internet across the archipelago.
What it's used for
Addressing for satellite-delivered connectivity. The AS announces 9 IPv4 prefixes totalling 2,304 addresses, all /24s scattered across 203.99.96.0–203.99.127.0, and no IPv6. Every sampled PTR is first-party and sequential — 203-99-104-5.telkomsat.co.id, 203-99-127-133.telkomsat.co.id and so on — the generic template an operator stamps across space it assigns to service endpoints. Telkomsat's VSAT customers are public facilities in frontier districts, enterprises outside fibre coverage, ATM and kiosk networks, maritime users, and 4G backhaul in remote areas, so the addresses behind those PTRs are terminals and gateways, not a consumer broadband pool.
Notable
This is carrier-assigned business and public-sector space, and the small, tidy footprint is why. 2,304 addresses across nine /24s with 2 observed BGP neighbours is not a transit network — a wholesale carrier peers with hundreds of ASes — and it is far too small to be the eyeball network of a country of 280 million. Telkom Indonesia's consumer subscribers live in its other ASes; this one carries the satellite arm's own service addressing.
Interesting
Satellite space geolocates badly. A Telkomsat address terminates wherever the VSAT dish is — Papua, a ship, a remote ATM — even though the routing and the teleport sit in Java.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, 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: 447 networks and 1,848 prefixes, as published 2026-10-31. 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.
