Resolver Caching

Resolver caching is a process used by internet systems to improve the efficiency of translating website names (like www.example.com) into their corresponding numerical addresses (IP addresses). When a DNS resolver (a server that performs this translation) looks up a website, it stores the result temporarily. If the same website is requested again soon after, the resolver can quickly provide the answer from its cache instead of performing a new, time-consuming lookup. This caching speeds up internet browsing and reduces network traffic, ensuring faster responses and less load on authoritative DNS servers.
