Nameserver
A server that stores DNS records and responds to queries about domain names.
Nameservers are specialized servers that hold DNS records for domains. When someone tries to access your website, nameservers tell them where to find it.
Every domain has at least two nameservers for redundancy. They typically look like:
- ns1.registrar.com
- ns2.registrar.com
Types of Nameservers:
- Registrar Nameservers: Default option when you register
- Web Host Nameservers: Provided when you sign up for hosting
- Third-party DNS: Cloudflare, Route53, DNSimple
Changing Nameservers: When you point nameservers to a different provider:
- All DNS management moves to that provider
- Records at your registrar are no longer used
- You must recreate records at the new location
- Changes take 24-48 hours to fully propagate
Nameserver Requirements:
- Minimum of 2 nameservers (redundancy)
- Must respond to DNS queries
- Should be geographically distributed
- Need to be configured for your domain
Why It Matters
Nameservers determine where your DNS is managed. Choosing the right nameserver setup affects website speed, reliability, and how easily you can manage DNS records.
Practical Example
When you sign up for Cloudflare, they give you nameservers like 'anna.ns.cloudflare.com'. You enter these at your registrar, and all DNS management then happens in Cloudflare's dashboard.
