Summary

CDG Group

Thailand · AI-generated

business it thailand corporate

CONTROL-DATA-CSLOXINFO-AS-TH is operated by CDG Group, a Thai information technology conglomerate.

What it's used for

  • The address space is registered under the netname CDGGROUP-TH with registrant CONTROL DATA (THAILAND) COMPANY LIMITED, indicating internal corporate infrastructure.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 1 observed neighbour, a ratio consistent with a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal business operations, IT services, and administrative endpoints for the CDG Group and its affiliates.

Notable

  • Registrants for both announced prefixes align with the announcer, identifying CONTROL DATA (THAILAND) COMPANY LIMITED as the consistent holder.
  • Control Data (Thailand) Ltd. was originally a subsidiary of Control Data (US) and has since evolved into the CDG Group, a diversified IT company in Thailand.
  • The inventory consists of two distinct IPv4 blocks: 202.22.14.0/23 and 157.179.6.0/24, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
