Once it has that information, the browser can store it in its local cache. Then, the next time I type in that website address, the browser will look for its DNS information in the local cache first and be able to find the site more quickly.
The problem is that sometimes dangerous IP addresses or corrupted results can be cached and need to be removed. The DNS cache can also impact your ability to connect to the internet or cause other issues. This can help resolve security, internet connectivity, and other issues. This specifies a period of time in seconds in which the DNS record for a site remains valid.
Within this time period, any queries to the website are answered from the local cache without the help of the DNS server. Once the TTL expires, the entry will be removed from the cache. However, there are reasons you may need to force a DNS flush rather than wait for the TTL of all the entries to expire. These reasons may have to do with security, technical problems, or data privacy.
DNS spoofing — also known as DNS cache poisoning — is an attack in which bad actors gain access to your DNS cache and alter the information in order to redirect you to the wrong sites. In some cases, they will redirect you to a fraudulent website that resembles its intended destination so that you enter in sensitive information, like your online banking login information. In that case, the DNS information on your computer may not get updated right away and you could end up seeing a error or an outdated version of a site when you try to visit.
