Pro Tip

Lower your TTL (Time To Live) to 300 seconds before making DNS changes. This speeds up propagation by telling DNS servers to refresh more frequently.

DNS FAQ

What is DNS?
DNS (Domain Name System) is like the internet's phone book. It translates human-readable domain names (like namemy.app) into IP addresses (like 192.0.2.1) that computers use to communicate. Without DNS, you'd have to remember IP addresses instead of website names.
What is an A record?
An A record (Address record) points your domain to an IP address. It's the most basic DNS record, telling browsers which server hosts your website. For example, an A record might point 'example.com' to '192.0.2.1'.
What is a CNAME record?
A CNAME (Canonical Name) record creates an alias from one domain to another. Common uses include pointing 'www.example.com' to 'example.com', or connecting your domain to services like Vercel or Netlify that provide their own hostnames.
How long does DNS take to update?
DNS changes typically propagate within minutes to a few hours, though it can take up to 48 hours in rare cases. This delay is called 'propagation time.' namemyapp uses Cloudflare DNS for faster propagation, usually under 5 minutes.
What are MX records for?
MX (Mail Exchange) records specify which servers handle email for your domain. If you want emails sent to [email protected] to work, you need MX records pointing to your email provider (like Google Workspace or your own mail server).
Do I need to manage DNS myself?
Not necessarily. namemyapp provides one-click DNS presets for popular platforms like Vercel, Netlify, and Cloudflare. Select your hosting provider, and we automatically configure the correct DNS records. You can also manage records manually if needed.
