Internet address. For example, bartvisions.cz is a second-order domain. blog.bartvisions.cz would then be a third-order address. A first-level domain, or TLD (top level domain), is then a national domain name (.cz, .pl, .org…).
Direct marketing, or directly reaching a customer, business partner or other end user. The most common form of direct marketing in the Internet environment is email sales communications, known as newsletters, which are sent to customers upon approval.

DNS or Domain Name System. This is a stored database of domain names containing information about which server the domain is on.
DNSSEC is the security of a DNS server with a unique key through what is known as asymmetric encryption. This means that it uses two keys. One for encryption and one for decryption. The first key is used by the domain owner to sign and encrypt the data they put on the domain. The others then use the public key to authenticate the data. This security prevents attackers from spoofing the IP address of the domain you want to visit and redirecting it to a spoofed website. You can secure your domain using DNSSEC by contacting your registrar. However, it is important to have your connection secured as well, your internet provider will arrange this for you.
This is an abbreviation of DomainKeys Identified Mail, or domain key signed email. DKIM is a type of electronic signature that protects email recipients from spam. Email signed with DKIM has no claims on end users. You can generate this key/signature yourself in most freemail services (in Gmail, you can generate the key via Apps - Gmail - Authentication - DKIM), preventing your emails from falling into spam or promotions for your recipients. DKIM works on a similar principle to SPF, but is a more modern and secure way to verify the sender's identity. The DKIM signature is decrypted by the email service itself based on the public DNS key of the domain.
