Summary
National Telecom Public Company Limited (THAI-GATEWAY)
transit legacy
THAI-GATEWAY is Thailand's state-owned international internet gateway,
originally run by the Communications Authority of Thailand (CAT) and now held by
National Telecom Public Company Limited (NT).
What it's used for
- International IP transit and gateway services carrying Thai traffic to and from the rest of the world.
- Wholesale connectivity sold on to Thai ISPs and enterprises.
Notable
- The registry record moved from CAT Telecom to National Telecom after Thailand merged its two state telecom operators (CAT and TOT) into a single entity, National Telecom, in 2021. The
THAI-GATEWAYhandle survives from the CAT era. - For much of Thailand's early internet history, the country's external connectivity funnelled through the CAT gateway, which is why this ASN sits so low in the number space.
