Frequently Asked Questions
Will changing my DNS server speed up my internet?▾
It can improve the time it takes to look up website addresses, which may make pages start loading slightly faster. However, it will not increase your overall download or upload speeds, as those are determined by your internet plan.
Is it safe to use a third-party DNS server?▾
Yes, reputable DNS providers like Cloudflare (1.1.1.1) and Google (8.8.8.8) are safe and often faster than your ISP's default DNS. Some also offer additional privacy protections and malware filtering.
Do I need to restart my computer after changing DNS?▾
Usually not. Changes take effect immediately for new connections. If you notice issues, try flushing your DNS cache or restarting your browser first. A full restart is rarely necessary.
