Summary
Arcnet (NTT MSC Sdn Bhd)
isp enterprise datacenter malaysia
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.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
