How to Boost Internet Speed with DNS Settings

Understanding DNS

• DNS Definition: DNS stands for Domain Name System, which translates website host names into numerical IP addresses, guiding computers to the correct server.
• Analogy: Similar to how phone books translate a person's name into a phone number.

Impact on Internet Speed

• Latency: Slow DNS connections can cause delays (latency) in web page loading.
• ISP DNS: Most major ISPs provide fast default DNS servers, minimizing the potential speed benefit from changing DNS.

Benefits of Changing DNS

• Public DNS: Common suggestions include Cloudflare or Google DNS but may only slightly reduce latency by 10-20 milliseconds.
• Filtering DNS: More beneficial for blocking ads, potentially improving browsing speed and experience.

Advantages of Filtering DNS

• Ad Load Reduction: Reduces latency by minimizing DNS requests for ads, which can slow down browsing due to additional scripts.
• Improved Performance: Filtering DNS blocks these ads and scripts before they load, enhancing browser performance.
• CPU and Battery Benefits: No software overhead, reduces CPU load and battery use.

Mobile and Laptop Considerations

• Universal Protection: Filtering DNS applies irrespective of location, unlike ISP or public Wi-Fi DNS settings.
• Difference from Ad Blockers: Filtering DNS can't remove ad spaces; it prevents the ads from loading entirely.

Conclusion

• Does not require software installation; adjust settings on an OS or router level.
• Linked guidance is available for DNS server adjustments.
