Summary

CIMB Securities (Thailand)

Thailand · AI-generated

business finance corporate

PROENKS-AS-AP is held by CIMB Securities (Thailand) Company Limited.

What it's used for

  • The space carries corporate network traffic, indicated by the registrant netname INET-TH and reverse DNS entries pointing to inter.net.th.
  • The AS announces 256 IPv4 addresses within a single prefix (203.150.42.0/24) and maintains 1 observed neighbour, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal systems for a securities firm, supporting trading, administrative, and client-facing business operations.

Notable

  • The RDAP registrant for the announced prefix is IRT-INET-TH with netname INET-TH, which differs from the AS holder name but aligns with the corporate identity of the operator.
  • The address inventory is compact, consisting of a single /24 block, which fits the profile of a specific branch or headquarters site for a financial institution.

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 1,771 prefixes, as published 2026-10-15. 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.
