How to Add a Primary Domain or Subdomain in Namecheap?

Overview​

This guide demonstrates how to add a root domain or subdomain in Namecheap and configure the DNS records required by uSpeedo.

Prerequisite: You already have a Namecheap account.

Although this guide is as detailed as possible, you may still encounter issues when configuring DNS records. If problems arise, we recommend contacting Namecheap official support directly—they can identify and resolve issues faster (or provide guidance on next steps).

Choose Root Domain or Subdomain​

Before you start, you need to decide whether to use:

  • Primary Domain
  • or Subdomain

Concept Explanation​

  • Root Domain Examples:
    • uspeedo.com
    • google.com
  • Subdomain Examples:
    • mail.uspeedo.com
    • mail.google.com

👉 Rule: A subdomain adds a prefix (one or more) to the root domain.

📌 Recommendation: Use a subdomain first.

After Making Your Selection​

  1. Add the domain/subdomain in the uSpeedo Console
  2. The system will automatically generate the corresponding DNS records

Add a Domain​

Three methods are supported:

Method 1: Register a New Domain​

Purchase a new domain directly in Namecheap.

Steps:

  1. Log in to Namecheap img

  2. Enter the domain you want to purchase img

  3. Complete payment and registration img

Method 2: Transfer a Domain​

Transfer a domain from another registrar to Namecheap.

Keep your current registrar, but switch DNS hosting to Namecheap.

If your domain is registered on another platform:

  1. Log in to Namecheap img

  2. Go to Domains → FreeDNS img

  3. Enter your domain and click Get DNS img

  4. Add to cart and click Set up DNS img

  5. Obtain the NS records provided by Namecheap

  6. Update the NS records at your original registrar to the values provided by Namecheap

👉 This article focuses on Method 1 and Method 3.

Update NS Records (Critical)​

If you are migrating from another DNS service: 👉 You must update the NS (Name Server) records.

Otherwise: ❌ uSpeedo will be unable to verify the DNS configuration.
