Summary

JasTel Network

Thailand · AI-generated

transit legacy

JASTEL-NETWORK-IDC is JasTel Network Company Limited, the carrier subsidiary of Thailand's Jasmine International (JAS). It sells leased circuits, IP transit, international gateway service and data-centre colocation to businesses.

What it's used for

  • Corporate leased-line and transit customers. Reverse DNS across 203.156.0.0/17 and 203.147.0.0/18 follows the pattern N.N.N.N.static-corp.jastel.co.th — explicitly static corporate addressing, with no dynamic or subscriber-style names anywhere.
  • Customer networks sit directly in the space under their own names: mail.amway.co.th and a NAT gateway at webster.ac.th (Webster University Thailand) both resolve inside these blocks.
  • Internet data centre and colocation, which is what the -IDC in the handle refers to.

Notable

  • This is not the Jasmine group's consumer ISP. The eyeball brand is 3BB, on a different ASN. AS7616 carries business circuits and hosted equipment; classifying it as residential from the group name would be wrong.
  • JasTel holds a Thai international gateway licence, so a share of this space is genuinely wholesale-carrier infrastructure rather than end-customer addressing.

Interesting

  • Jasmine's structure separates the wholesale carrier from the retail ISP quite cleanly, which is unusual: many operators run both on one AS and leave a confusing mix of corporate and subscriber rDNS in the same prefix. Here, the static-corp naming makes the boundary explicit.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
