Pushing.net helps buyers find domain names to rent/lease for the buyer's own website.

Leasing is simple: search for a domain you like, make an offer, and if the offer is accepted, you can do what you want with the domain.

Many uses include a) pointing the domain to a newly created website, b) pointing the domain to your existing website, or simply c) doing nothing with the domain, but preventing your competition from being able to use it.
