Name server hardening is a critical aspect of securing the foundational elements of DNS infrastructure against a wide range of threats, including denial-of-service attacks, unauthorized access, data leakage, spoofing, and protocol abuse. As the authoritative or recursive resolvers that handle domain name resolution requests, name servers are integral to the functioning of virtually every online…

Performing a name server health check is a fundamental task for network administrators, domain owners, and IT teams responsible for maintaining the reliability and performance of DNS infrastructure. Name servers are essential to the proper functioning of internet services, translating human-readable domain names into IP addresses that machines can use. If a name server is…

In the world of DNS infrastructure, two of the most widely used name server software solutions are Unbound and BIND. Both serve essential roles in domain name resolution and network functionality, but they are built with different design philosophies, use cases, and technical priorities. Comparing Unbound and BIND reveals significant contrasts in their architectures, features,…

DNS hijacking is a serious and increasingly sophisticated threat that can compromise the integrity, availability, and confidentiality of online services by rerouting traffic intended for legitimate domains to malicious destinations. At the core of this attack vector lies the manipulation or exploitation of name server configurations, making name server security a critical defense mechanism against…

Monitoring name servers is a critical component of maintaining a secure, reliable, and high-performing DNS infrastructure. As the backbone of domain name resolution, name servers are responsible for responding to queries that direct internet traffic to websites, applications, and services. If a name server fails, misbehaves, or is misconfigured, the consequences can include service downtime,…

Switching name servers for a domain is a process that many website owners and administrators will encounter at some point, whether due to migrating to a new hosting provider, adopting a third-party DNS service, or taking greater control of DNS configurations. While the process itself is relatively straightforward, executing it without causing downtime requires precise…

In the complex architecture of the Domain Name System (DNS), two types of name servers perform distinct but complementary roles: recursive name servers and authoritative name servers. Understanding the differences between these two is essential for anyone involved in web hosting, IT administration, or cybersecurity, as each plays a crucial part in the process of…

Securing your name servers is a critical aspect of maintaining a reliable and trustworthy internet presence. Name servers form the backbone of the Domain Name System (DNS), handling queries that resolve domain names into IP addresses. If these servers are compromised or misconfigured, the consequences can be severe, ranging from service outages to traffic redirection,…

Setting up your own name server is a significant step in gaining full control over your domain’s DNS infrastructure. While many rely on third-party DNS hosting services provided by registrars or web hosting companies, there are scenarios where running your own name server is desirable or even necessary. It can offer advanced customization, improved security,…

In the vast digital landscape of the internet, where websites and online services reside across an intricate network of computers, name servers play a crucial yet often overlooked role.
