Domains or domain names are virtual addresses in the internet real addresses. Every year thousands of domains are registered, bought and sold in the aftermarket. With popularity of internet growing, it won't slowdown anytime soon - In fact it'll increase over time. This .org TLD domaen.org is a misspelling of 'domain' with just one letter 'i' replaced with 'e'. There is a possibility of even type in traffic when people manually typing in the browser. Potential for domainers.
Great news! Domain Domaen.org has been registered in the past and previous domain owner(s) may have forgot to renew or dropped it.
