As part of your internet service, the Internet Service Provider (ISP) also provides the local network with the necessary settings, including the Domain Name System (DNS) addresses, which allow you to access your favorite websites and online services and download files.
The only caveat is that the ISP's DNS servers are usually not very private, slower than other services, and can be unreliable. However, you can always use different resolvers from third-party companies to improve your internet experience on Windows 10.
