AS10204 — ARCNET-NTTMSC-MY Arcnet NTT MSC ISP

AS10204 announces 8 IPv4 prefixes covering 23,552 addresses and 2 IPv6 prefixes.

About this network

ARCNET-NTTMSC-MY is Arcnet, the internet-service brand of NTT MSC Sdn Bhd — NTT Communications' Malaysian arm, based in Cyberjaya and one of the original MSC Status companies of Malaysia's Multimedia Super Corridor programme.

What it's used for

• Corporate internet access, private WAN and managed services for Malaysian businesses, plus data-centre and cloud services from NTT's Nexcenter facility. The reverse DNS sample lands on draas-demo-esx.nttmsc.my — a disaster-recovery-as-a-service demonstration hypervisor, which is exactly the kind of first-party managed-hosting asset you would expect to find in this space.

Notable

This is a business ISP, not an eyeball network and not a wholesale carrier. RIS sees 29 announced IPv4 prefixes covering 23,552 addresses, 2 IPv6 prefixes, and 19 observed neighbours. Nineteen peers is the tell: far more than the two or three a pure enterprise keeps, far fewer than the hundreds a transit carrier accumulates. That is the profile of a regional ISP that peers locally, buys upstream transit, and sells connectivity to corporate customers.

The prefixes are a mix of an old aggregate — 203.115.192.0/18, deaggregated into /19s, /20s and /24s for traffic engineering — and newer scattered APNIC blocks (45.115.220.0/22, 43.231.224.0/22, 103.229.32.0/22). That is normal growth for a two-decade-old operator, not address brokering: the space is announced by the operator itself and carries its own named infrastructure.

Interesting

The Arcnet brand predates NTT's ownership and survived it. NTT's global Tier-1 backbone is a different network entirely; this AS is the local Malaysian service provider that sits behind it.
