Summary
Centrin (PT Centrin Utama)
isp residential business legacy
AS9326 (CENTRIN-AS-AP) is held by PT Centrin Utama, part of the Indonesian internet provider trading as Centrin Online (centrin.net.id), with registry contacts in Bandung, West Java. RIS sees 38 IPv4 prefixes carrying 42,496 addresses, 2 IPv6 prefixes, and 7 observed BGP neighbours.
What it's used for
Centrin is an access ISP serving Indonesian consumers and businesses, and the numbers fit: forty thousand addresses reached through a handful of neighbours is an eyeball network buying transit from a few Indonesian carriers, not a wholesale operator. Directory records show a small number of downstream Indonesian networks hanging off it, which is normal for an established local ISP that also resells connectivity, but nowhere near the peering breadth of a transit provider.
The address space is a long-held APNIC allocation built up over time: a 124.153.0.0/18, the 202.146.224.0/19 that has been Centrin's home range for years, a 113.11.128.0/19, plus 202.57.x, 203.166.x and a tail of /23s and /24s. Two IPv6 blocks (2406:b200::/32 and 2402:4100::/32) mean the network is dual-stacked. The sampled reverse DNS lands on the provider's own infrastructure rather than customer pools — a nameserver and a host named uranus.centrin.net.id — showing that the operator runs its service platform inside the same space it assigns to customers.
Notable
- Two separately allocated IPv6 /32s under one ASN is unusual and suggests resources gathered across more than one entity in the Centrin group.
- Registry records for the group also carry the
prima.net.iddomain, matching the Centrin Online Prima trading name.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
