According to its WHOIS record, SNTRIC.NET was created on January 6, 2015 and expires on January 6, 2018. That makes the domain about 11 years old. It is registered through FastDomain Inc. (IANA ID 1154) and is past its expiry date. Its record is locked against unauthorised transfer. The registrant is listed in Pakistan. DNS is served by ns1.bluehost.com and ns2.bluehost.com. Privacy services replace the owner's contact details in the public record with those of a proxy, which is common for personal registrations. Renewals are usually made for one to ten years at a time, so an expiry date far in the future shows a long-term commitment to the name. Nameservers decide where a domain's DNS is hosted, so a change of nameservers usually means the website or email moved to a new provider. Managed DNS providers are often used for speed, security and protection against attacks. Domains that are not renewed before their expiry date normally enter a grace and redemption period before they can be registered again.
Whois Data Center has 4 historical WHOIS snapshots for SNTRIC.NET. The most recent capture is from July 8, 2017. Each snapshot is a dated copy of the public WHOIS record as it looked when it was collected. Investigators use dated records to establish who controlled a domain at a specific point in time. A long history with few changes usually points to a stable owner, while frequent changes can signal a transfer or a resale. Snapshots are collected over time, so the gaps between them depend on how often the record was checked.
In the period from January 8, 2015 to July 8, 2017, 10 fields of the record were modified. The expiry date moved from January 6, 2016 to January 6, 2018, which shows the domain was renewed. Each change listed here can be checked against the original snapshots further down the page.
