How to Configure DNS Settings for Your Custom Short URL Domain ​

The Domain Name System (DNS) allows a web browser to translate a domain name to the correct IP address of a website. If you want to use your own domain with Cellcast to generate custom short links, you'll need to configure a few DNS settings through your domain registrar.

What You’ll Need to Set Up ​

You’ll need to set up A Records or CNAME Records, depending on whether you’re using a root domain or a subdomain.

For a Domain (Root Domain) ​

If you're using your main domain name (like yourdomain.com) as your custom short URL, you'll need to configure A Records to point to Cellcast’s IP address.

Step-by-step Instructions: ​

  1. Log in to your domain registrar's website.

  2. Select the domain you want to modify.

  3. Navigate to the DNS settings section. This is usually labeled as DNS Management, DNS Records, or Advanced DNS.

  4. Locate any existing A Records for the root domain (@).

  5. Update or create the following A Records:

    Record TypeHostnamePoints To
    A@54.253.79.30
    A@13.54.56.228

  6. Remove any other A Records pointing to different IPs.

  7. Save your changes.

⚠️ Important: If you see the word "parked" in an A Record, replace it with Cellcast’s IP address.

For a Subdomain (e.g., go.yourdomain.com) ​

If you're using a subdomain as your custom short link, you’ll need to configure a CNAME Record to point to Cellcast.

Step-by-step Instructions: ​

  1. Log in to your domain registrar’s website.

  2. Select the domain associated with your subdomain.

  3. Navigate to the DNS settings section.

  4. Locate or create a CNAME Record with the following details:

    Record TypeHostnamePoints To
    CNAMEyour chosen subdomain?????????????

    For example, if your short link is go.yourdomain.com, enter go as the Hostname.

  5. (Optional) To also configure a www version of your custom short link, add another CNAME:

    Record TypeHostnamePoints To
    CNAMEwww?????????????

  6. Save your changes.

Final Steps ​

Once you’ve configured your DNS settings:

  1. Go to Cellcast > Settings > Custom Domain.
  2. Submit your custom domain for verification.
  3. Wait for admin approval — you’ll be notified once it’s active.
