Summary

CIMB Securities (Thailand)

Thailand · AI-generated

business financial thailand

CIMB-AS-AP is held by CIMB Securities (Thailand) Co.,Ltd.

What it's used for

  • The address space carries corporate and leased infrastructure, evidenced by netnames SYMPHONY-INTERNET-DIA and TrueCorporate and reverse DNS entries pointing to static.asianet.co.th.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints for a securities firm, including office workers and web/API services, rather than subscriber eyeballs or public internet access.

Notable

  • Registrants differ from the announcer, with SYMPHONY COMMUNICATION PUBLIC COMPANY LIMITED and TRUE IP ADMINISTRATION listed for the respective prefixes, suggesting leased or historically allocated space.
  • The address inventory is small and finely subdivided into two /24 blocks, consistent with an internal corporate estate segmented by site or service.

Reputation

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
