Overview 

Nameservers and DNS records are both part of how a domain works, but they serve different roles.

• Nameservers define which DNS provider is authoritative for your domain
• DNS records define how your domain behaves (website, email, etc.)

Nameservers

Nameservers tell the internet which DNS provider holds the authoritative DNS zone for your domain.

• Set at the domain registrar
• Point to a DNS provider (e.g.,Rebel, Cloudflare)
• Control where DNS records are managed

👉 Changing nameservers = switching DNS providers

DNS Records

DNS records are stored at the DNS provider and define how your domain functions.

Common records include:

• A record → points your domain to a server (website)
• MX record → routes email
• CNAME → aliases one domain to another
• TXT → used for verification and email security (SPF, DKIM, DMARC)

👉 Updating DNS records = changing how your services work

Key Difference

• Nameservers = who manages DNS
• DNS records = what the domain does

Simple Example

• Change nameservers → move DNS control to a new provider
• Change an A record → point your website to a new server

Key Takeaway

Nameservers control where DNS is managed, while DNS records control how your domain behaves.
