Why should you change your Mac DNS server?
A Domain Name System (DNS) server responds to requests from a device and resolves them into a valid IP address. In this way, users can enter the domain name of a web address in a browser instead of entering the full web address.While a server is usually automatically assigned to you, in certain circumstances, it may make sense to change your DNS server settings. The most common reasons for this are as follows:
- Overload: If a DNS server is overloaded, it can take a long time to display a website. As a result, you may receive a timeout notification and not be able to access the website. If the DNS server is not responding, changing the server may resolve the situation.
- Security: Some DNS servers can block potentially malicious websites and thus prevent malware. On the other hand, some servers store search queries and pass them on for commercial use. You can prevent this by changing the DNS settings.
- Filter: As previously mentioned, some servers filter websites. To access a blocked website, change the DNS server on your Mac to prevent a filter list from being used.
