Thailand · AI-generated

business th ptt digital

PTTDIGITAL-AS-AP is operated by PTT Digital Solutions Company Limited.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the netname PTTDIGITAL-TH and registrant PTT Digital Solutions Company Limited for both announced IPv4 blocks.
  • The AS announces 3,072 IPv4 addresses across 2 prefixes and 16 IPv6 prefixes, with 3 observed neighbours, indicating a business network with limited peering.
  • Traffic consists of internal corporate systems, web/API endpoints, and digital services for PTT Group entities, as PTT Digital Solutions provides IT design, development, and maintenance services.

Notable

  • Registrants agree with the announcer, with both prefixes registered to PTT Digital Solutions Company Limited under the netname PTTDIGITAL-TH.
  • The address inventory consists of two IPv4 blocks (202.44.0.0/21 and 175.176.220.0/22) and a large IPv6 allocation under 2401:a580::/40, typical for a corporate digital services provider.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
