The best for registering domain names and transferring multiple names at once (costs start at $2.19 per year).

NameSilo is a domain name registrar that provides domain name registration, transfer, bidding, and other services. It includes a search tool that allows you to search for one or more domain names.

You get free domain privacy protection, as well as a substantial discount on domain registration and on the transfer of a selected group of domains.

In addition, all domains come with:

DNS management tools.
Free privacy protection of the domain.
Supports Registry Lock status.
Domain Protector.
Domain portfolio management.

NameSilo also includes an online store that shows all the domains by their owners as well as non-renewed domains. You can also buy selected domains through an auction, or by paying directly to the buyer (note: the author is probably wrong and should be “paying directly to the seller”).

In addition, you can transfer existing domain names into NameSilo in three steps. All you have to do is confirm your domain name, enter your EEP code into the domain transfer form, and add the domain to the shopping cart (note: the EEP code is used to verify that you are the owner of the domain). The domain will be transferred in 5-7 days.
