sirsi.net

According to its WHOIS record, SIRSI.NET was created on October 27, 1999 and expires on October 27, 2030. That makes the domain about 27 years old. It is registered through Network Solutions; LLC (IANA ID 2) and is active. Its record is locked against unauthorised transfer. The owner has renewed it well ahead, up to 2030. The registrant is listed in United States. DNS is served by coco.ns.cloudflare.com and damien.ns.cloudflare.com, which means its DNS is run by Cloudflare. When a domain uses its own nameservers, the owner runs the DNS directly instead of relying on a hosting or DNS provider. 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. 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. Status flags such as transfer or delete locks are set by the registrar or registry to protect a domain from unauthorised changes. Managed DNS providers are often used for speed, security and protection against attacks. An older registration date is often seen as a sign of an established website, although age alone says nothing about who owns it today.
