c21online.com

C21ONLINE.COM was registered on February 10, 1999, and is set to expire on February 10, 2027. Its age is about 27 years. The domain is managed by CSC Corporate Domains, Inc. (IANA ID 299) and is active. Only 88 days remain until it expires, so it needs to be renewed soon to stay with its current owner. Public WHOIS names Century 21 Real Estate LLC as the registrant organisation, with United States as the country. An older registration date is often seen as a sign of an established website, although age alone says nothing about who owns it today. Status flags such as transfer or delete locks are set by the registrar or registry to protect a domain from unauthorised changes. Changes to the registrant organisation can point to a sale, a merger or simply an update of company details. 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. Privacy services replace the owner's contact details in the public record with those of a proxy, which is common for personal registrations. A registrar transfer moves the management of a domain from one company to another without changing the domain name itself. Domains that are not renewed before their expiry date normally enter a grace and redemption period before they can be registered again.
