What it's used for

  • The AS announces 1280 IPv4 addresses across 5 prefixes and maintains 4 observed neighbours, a ratio consistent with a business access or enterprise connectivity provider rather than a large-scale residential ISP or transit carrier.
  • Traffic from this AS consists of corporate data, VoIP, and web endpoints for the more than 400 companies Infonet serves, including multinational corporations and domestic enterprises with nationwide branches.

Notable

  • The inventory consists of five /24 blocks, all located in Thailand, with no IPv6 prefixes announced.

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 1,772 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.
