When you enter a domain name into your browser, the DNS resolver retrieves the corresponding IP address from DNS servers. This process involves several stages, including queries to root servers, TLD (Top-Level Domain) servers, and authoritative DNS servers.

DNS is essential for the operation of the internet, enabling users to access websites using easily memorable domain names rather than complex IP addresses. The internet would be far more difficult to navigate without DNS.

DNS security identifies the locations where malicious domains are staged. Secure DNS servers reject queries arriving from these staging sites over any port or protocol to prevent attempts at infiltration and exfiltration. By connecting to your network, compromised devices are prevented from trying to spread any malware thanks to DNS-layer protection. It also prevents your DNS server from responding to possible hijacker attacks.

First, choose the name you want to register for, usually your company or website name. It’s best to select a name that is short, easy to understand, and sounds good when spoken aloud. Then, check if the name is available. If your preferred name is already taken with the .com top-level domain, consider other available options. Finally, add your top choices to your cart and complete the registration process.

Domain Name System (DNS) Zones are any discrete, linking domain name space segment inside the DNS that has administrative authority assigned to a single administrative space, facilitating more seamless administration over DNS components. The web's namespace is arranged into subdomains that are nested beneath the DNS root domain. This tree's individual domains could serve as hubs for management and administrative authority delegation.

There are four main attack vectors that most DNS threats belong to. Volumetric assaults overload DNS servers with requests, making them sluggish or even unresponsive. Protocol abuse attacks employ DNS inadvertently to carry out phishing campaigns or data exfiltration. Slow drip or stealth DNS attacks cause service degradation or interruption by sending out a continuous stream of targeted requests that exceed the DNS server's capability. Exploits make use of holes or weaknesses in operating systems, protocols, or DNS services.
