Role of Public DNS
Public DNS (Domain Name System) servers are a crucial component of internet infrastructure. They are responsible for resolving domain names (e.g., www.example.com) entered by users into corresponding IP addresses (e.g., 192.0.2.1), allowing browsers to find and access websites. Using public DNS servers offers the following advantages:
- Improve Resolution Speed: Choosing a DNS server that is geographically close and has a fast response speed can accelerate the domain name resolution process, thereby improving web page loading speed.
- Enhance Network Security: Some public DNS providers filter malicious websites and phishing sites, enhancing online security.
- Circumvent Network Restrictions: In some cases, changing public DNS can help users bypass local operator's DNS hijacking or resolution failures.
- Stability and Reliability: Large public DNS services typically have more robust infrastructure and disaster recovery capabilities, ensuring stable operation of resolution services.
