About this network

Samart Infonet is a Thai internet service provider, part of the SAMART Group of ICT companies, headquartered in Pak Kret, Nonthaburi.

What it's used for

• Corporate and government internet access in Thailand: leased line, MPLS, G.SHDSL and FTTx connectivity.
• Co-location and cloud hosting services sold alongside the connectivity.

Notable

• Samart Infonet's customer base skews to government agencies and business organisations rather than home broadband, so the address space behaves more like enterprise and hosting space than consumer eyeball space.
• SAMART Group is a long-established Thai technology conglomerate with several companies listed on the Stock Exchange of Thailand; Samart Infonet is the group's ISP arm.
