A caching DNS server, also known as a DNS resolver or DNS cache, is a crucial component of the Domain Name System (DNS). Its primary function is to temporarily store DNS records to reduce the workload on authoritative DNS servers and improve the efficiency of DNS resolution. Here’s how caching DNS servers work and their […]

Secondary DNS servers, also known as secondary name servers or slave DNS servers, are a crucial component of the Domain Name System (DNS). These servers work in conjunction with primary (master) DNS servers to provide redundancy and fault tolerance in DNS resolution. Here’s an overview of secondary DNS servers, their functions, and why they are […]

Top-Level Domain (TLD) DNS servers, also known as authoritative DNS servers for TLDs, are responsible for managing the DNS records of specific top-level domains in the Domain Name System (DNS). These servers play a vital role in the DNS hierarchy, as they maintain the authoritative information for TLDs, such as .com, .org, .net, and country-code […]

Root DNS servers, also known as root name servers, are an essential part of the Domain Name System (DNS) infrastructure. These servers are responsible for the highest level of DNS hierarchy and play a pivotal role in the DNS resolution process. Here’s an overview of root DNS servers, their functions, and their significance in the […]
