Summary

REDtone

Malaysia · AI-generated

cable dsl isp residential

The AS handle CNXNET-AS-MY is held by REDtone Engineering & Network Services Sdn Bhd.

What it's used for

  • The address space carries residential and business access traffic, evidenced by netnames RTC-NET, RTC-AS-AP, and RTC-MY, and reverse DNS entries such as ns4.redtone.com and 202-46-119-255.cnx.com.my.
  • The AS announces 22,528 IPv4 addresses across 12 prefixes and 6 IPv6 prefixes, while maintaining 32 observed neighbours, a ratio consistent with an access provider rather than a transit carrier.

Notable

  • Registrants are consistent with the announcer, listing CNX NOC; Redtone Engineering & Network Services Sdn Bhd for most prefixes and CNX NOC; REDtone Telecommunication Sdn Bhd for the REDTONE and REDTONE-NET blocks.
  • The inventory is a mixed estate of legacy 182.54.0.0/16 space and newer allocations in 203.142.0.0/16, 202.46.0.0/16, 103.21.0.0/16, and 43.251.0.0/16.

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: 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.
