DNS caching

DNS caching is the process where DNS servers temporarily store the information they receive about domain names and their corresponding IP addresses. When you type a website's name, your device asks a DNS server to find its IP address. If that server has the information saved from previous requests, it can quickly provide the IP address instead of needing to search for it again. This speeds up internet browsing and reduces the load on DNS servers, making the overall web experience faster and more efficient. Cached information is updated regularly to ensure accuracy.
