Autonomous systems

Holder names and prefix counts come from the RIPE NCC's RIPEstat Data API, fetched on 2026-09-06. Role and confidence come from the evidence linked in each row; "confirmed" means a PeeringDB or RIPEstat record, or the operator's own site, names the operator.

Mobile network codes

The MCC identifies the country and the MNC identifies the operator inside it. Together they appear in the IMSI of every SIM on the network and in device diagnostics; they are how a handset knows which network it is on.

About Progresif

Progresif is a mobile operator in Brunei owned by Darussalam Assets. The registry records no ASN under the Progresif name; its mobile traffic is carried by AS10094, the confirmed mobile-role ASN registered to Unified National Networks, the wholesale network shared by Brunei's retail providers. Progresif's network code is MCC 528 / MNC 02.

The registry records a single ASN for Progresif, and it belongs to another organisation. AS10094 is registered to Unified National Networks, the wholesale carrier that Brunei's retail mobile brands run on, and it is documented as the mobile-role ASN for Progresif traffic. At the last probe it was announced with 193 IPv4 prefixes and no IPv6 prefixes. PeeringDB lists the number under the name Unified National Networks with an information type of Cable/DSL/ISP. No ASN is registered in Progresif's own name.

An address whose origin ASN is AS10094 is routed by Unified National Networks. Progresif subscribers sit inside that space, but so do the customers of the country's other retail brands, so the ASN identifies the network rather than the seller. The registry documents no Progresif-specific range, and PeeringDB describes the network as Cable/DSL/ISP, so an address there could be mobile, fixed or enterprise. The origin ASN alone does not settle the access type.

Research note. Legal name Progresif Sdn Bhd / Progresif Cellular Sdn Bhd (PCSB); mcc-mnc.org lists MCC 528 MNC 02 as brand PCSB, operator Progresif Cellular Sdn Bhd, status Live (only UMTS2100 band on file there). Ownership: Wikipedia says 100% owned by Darussalam Assets (government-linked); The Scoop confirms Darussalam Assets as sole shareholder of DST, TelBru and Progresif. No ASN is registered under the Progresif name in RIPE asn.txt or RIPEstat (searchcomplete returned only unrelated domains); Progresif is a retail provider on the UNN single wholesale network, whose announced ASN is AS10094 (PeeringDB confirmed). 4G: Wikipedia Progresif article lists '4G+, 5G, Fiber Broadband' and a 2017 4G trial request; progresif.com advertises '5G Speed' prepaid plans. 5G: AITI release, 22 June 2023, names Progresif Sdn Bhd.

Questions

What is Progresif's ASN?
The registry records no confirmed ASN registered to Progresif. Its traffic is carried by AS10094, which is held by Unified National Networks, the wholesale operator running the single network that Brunei's retail providers sell mobile service on.
What is the MCC/MNC of Progresif?
Progresif uses MCC 528 with MNC 02, listed under the PCSB brand name. MCC 528 is Brunei's country code, and the registry holds no other network code for the operator.
Is an IP from AS10094 a Progresif IP?
Not from the ASN alone. AS10094 carries Brunei's retail mobile brands as well as fixed traffic, so an address routed through it may or may not belong to a Progresif subscriber, and it could be mobile, fixed or enterprise.

ASN and prefix data describe how the operator's networks are registered and announced. They do not identify an individual subscriber or where a device is, since carriers route traffic from many areas through shared gateways.
