sdm.co.th

According to its WHOIS record, SDM.CO.TH was created on December 27, 2017 and expires on December 26, 2023. That makes the domain about 8 years old. It is registered through THNIC and is past its expiry date. The registrant is listed in Thailand. DNS is served by cloud-linux01.thaidatahosting.com and cloud-linux02.thaidatahosting.com. The creation date shows when the name was first registered, while the expiry date shows how long the current registration has been paid for. When a domain uses its own nameservers, the owner runs the DNS directly instead of relying on a hosting or DNS provider. Domains that are not renewed before their expiry date normally enter a grace and redemption period before they can be registered again. Registry locks add an extra layer of protection for valuable names, because changes then need manual confirmation by the registry. Registrars are the companies accredited to sell and manage domain names, and the sponsoring registrar is the one currently responsible for this name. Changes to the registrant organisation can point to a sale, a merger or simply an update of company details. Public WHOIS records can show the registrant organisation and country, while many owners now hide personal details behind privacy services. Status flags such as transfer or delete locks are set by the registrar or registry to protect a domain from unauthorised changes. Privacy services replace the owner's contact details in the public record with those of a proxy, which is common for personal registrations. An older registration date is often seen as a sign of an established website, although age alone says nothing about who owns it today.

Whois Data Center has 5 historical WHOIS snapshots for SDM.CO.TH. The most recent capture is from December 21, 2022. Comparing snapshots makes it easy to see when the registrar, nameservers or status of a domain changed. Snapshots are collected over time, so the gaps between them depend on how often the record was checked. Historical records are useful for due diligence, brand protection and investigating the background of a website. These records help track changes in registration details, ownership signals and DNS over time. Security teams use WHOIS history to spot suspicious ownership changes and to link related domains. Each snapshot is a dated copy of the public WHOIS record as it looked when it was collected. Buyers often review the history of a domain before purchasing it, to see past owners and registrars. A long history with few changes usually points to a stable owner, while frequent changes can signal a transfer or a resale.

Nothing changed between the two most recent snapshots, so the record looks stable. Each change listed here can be checked against the original snapshots further down the page.
