Unclassified APNIC
Summary
Unified National Networks (Simpur)
SIMPUR-BN carries the legacy Simpur internet-service address space of Brunei Darussalam. The registry holder today is UNN-BN, Unified National Networks, the wholly state-owned company that took over all of Brunei's telecommunications infrastructure in September 2019 and now runs the country as a single wholesale network.
What it's used for
Access and service space for Brunei end users. The AS announces 25 IPv4 prefixes totalling 8,192 addresses and no IPv6, essentially the whole of 202.152.64.0/19 plus its component /24s deaggregated for traffic engineering. The sampled reverse DNS is uniform first-party ISP naming across the entire range — smp-64-5.simpur.net.bn, smp-83-133.simpur.net.bn, and so on — templated per-address PTRs of the sort an access ISP generates for a whole pool at once.
Notable
The routing shape is an eyeball network, not a carrier. Around 8,200 addresses against just 3 observed BGP neighbours means this network buys transit from a couple of upstreams and sells to nobody; a wholesale operator of any size would peer with hundreds. The Simpur brand outlived the company that coined it, which is a good reminder that a handle names history, not the current holder.
Interesting
Not all of this is subscriber space. One sampled address, 202.152.87.133, answers as ns1.egc.gov.bn — a nameserver of Brunei's E-Government National Centre. A small country's national network commonly hosts state infrastructure inside the same block as its retail customers, so individual addresses here can be government servers rather than households.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
