Summary

Thai Summit Autopart Industry

Thailand · AI-generated

business manufacturing corporate thailand

CSLOXINFO-INET-THAISUMMIT-AS is held by Thai Summit Autopart Industry Co.,Ltd.

What it's used for

  • The address space carries corporate infrastructure for an automotive parts manufacturer, with netnames Thaisummit-TH and thaisummitbgp-TH identifying the primary estate.
  • The AS announces 1024 IPv4 addresses across 4 prefixes and maintains 2 observed neighbours, a ratio consistent with a small internal corporate network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for a manufacturing company with facilities in Thailand, China, India, and Indonesia.

Notable

  • Registrants are split between Loxinfo IP Admins for the 58.137.x.x blocks and Internet Thailand Company Ltd. for the 203.150.x.x and 203.151.x.x blocks, indicating a mix of leased or historically allocated space.
  • The address inventory is finely subdivided into four /24 prefixes, reflecting site-by-site segmentation typical of a large industrial estate.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
