Website Nameserver Checker

Domains must have at least two nameservers for **redundancy and reliability**. If one nameserver goes offline or is unresponsive due to maintenance or a technical failure, the other nameservers can continue to answer DNS queries, ensuring uninterrupted website and email service. This setup is a fundamental requirement of the DNS system.

Nameserver changes are made through your **Domain Registrar** (e.g., GoDaddy, Namecheap) where you originally purchased the domain. You need to log into your registrar's control panel, find the DNS management section, and manually update the NS records to the new nameservers provided by your hosting or DNS provider (e.g., ns1.cloudflare.com).

The time it takes for a nameserver change to fully propagate globally is called **DNS propagation time**. It typically takes between **12 to 48 hours**. During this period, some users may see the old settings while others see the new ones, depending on their ISP's caching policies (TTL). Our tool can help you monitor this propagation.
