What is DNS caching?
To reduce the unnecessary load of DNS lookup requests and have the faster retrieval of web pages, DNS caching is done by saving the data locally on the system. The initial request might take a few milliseconds longer but the subsequent requests are answered faster since the data is already cached locally. Every DNS record is associated with a TTL (Time to Live) value which determines how long a particular DNS record should be cached locally before a new copy of the record is retrieved from DNS. When a request is made for a website, it first refers to the cache to get the IP address for that domain name and if record is not found then the request would pass on to the DNS server.
