Domain Name Servers
Explore the role of domain name servers (DNS) in translating domain names to IP addresses and discover how DNS load balancing distributes client requests across multiple servers. Understand different DNS record types and the benefits load balancing provides in enhancing performance, availability, and flexibility in software architectures.
Overview
Domain name servers (DNS) are key components of the internet that translate human-readable domain names (such as “google.com”) into numerical IP addresses that computers use to interact with one another.
How DNS works
When a user enters a domain name or clicks a hyperlink, the browser sends a request to a DNS server to resolve the domain name to an IP address.
