If a client send a query requesting for a particular web page to the DNS server and if the DNS server resolves the page from the other DNS servers & it will be store the same page in the DNS cache and it will give the response to the client with the requested page. If again the same web page is requested by any client then DNS server will get the web page from the DNS cache instead of again fetching the same page from the internet. With this there wont be any delay for the client to get the web page. This helps in bandwidth control. This is how the DNS server caching works.

What can be gained by using a caching only dns server?
Using a caching only DNS server has an easier set up. Also, using this type of DNS server can transfer information more securely if proper security measures are in place.
Which dns server configuration does not host any zones locally?
caching-only server
What type of DNS server is typically maintained by an ISP?

When you implement a caching-only DNS server for the first time is the cache server empty?
Yes....As the server starts to service client requests, the information is cached and builds with time.
Which two tasks are the responsibility of the local DNS server?

What can be gained by using caching-only DNS server?
Using a caching-only DNS server can significantly improve the speed and efficiency of DNS queries by storing previously resolved domain names and their corresponding IP addresses. This reduces the need to repeatedly query external DNS servers for the same information, resulting in faster response times for repeated requests. Additionally, it can help decrease overall network traffic and lower the load on upstream DNS servers. Overall, it enhances user experience by providing quicker access to frequently visited websites.

Where are the DNS records stored?
DNS records are stored in DNS servers, which are part of a distributed network that manages domain name resolution. These servers can be authoritative, containing the definitive records for a domain, or caching, temporarily storing records retrieved from authoritative servers. When a user queries a domain, the DNS resolver checks its cache first and, if not found, queries the appropriate authoritative DNS server to fetch the records.
Which functions might be included on a DNS server?
A DNS server typically performs functions such as resolving domain names to IP addresses, caching DNS queries to improve response times, and providing authoritative answers for specific domains. It may also support reverse DNS lookups, where IP addresses are translated back into domain names. Additionally, DNS servers can implement security features like DNSSEC to protect against certain types of attacks and can manage zone transfers to synchronize data between servers.
