TLD is a shortcut for top-level domain.
Top-level domain is called the end of a domain, which is always at the very back.
On nicsell you can purchase top-level domains with .de, .eu and .eu by auction.
In this case nicsell is our desire domain (also called domain or second-level-domain)
On the left side you'll find the third-level domain, also called subdomain (www.)
At the end you'll find the TLD, the top-level domain
Please note that the domains appears only 2 weeks before the expiry of the grace period
If you take a closer look, the domains are read from right to left.
