XHow do I create a subdomain and point it to a different IP address or host using an A record ?
To create a subdomain and point it to a different IP address or host using an A record, follow these steps:
1. **Access Your DNS Management Console:**
- Log in to the DNS management console provided by your domain registrar or DNS hosting provider. This is where you can manage your domain's DNS records.
2. **Locate the A Record Section:**
- Look for an option that allows you to manage or edit DNS records. It's usually labeled as "DNS Management," "DNS Settings," or similar.
3. **Create a New A Record:**
- Choose "A" or "A Record" from the record type dropdown menu. This is where you'll create the A record for your subdomain.
4. **Enter the Subdomain:**
- In the provided fields, enter the subdomain you want to create. For example, if you want to create a subdomain "blog" for the domain "example.com," you would enter "blog" in the subdomain field.
5. **Enter the New IP Address or Host:**
- In the field provided for the IP address or host, enter the new IP address or hostname to which you want the subdomain to point.
6. **Set TTL (Time to Live):**
- Specify the Time to Live value. This determines how long DNS servers will cache this information. The default is often fine, but you can adjust it if needed.
7. **Save or Update the A Record:**
- After entering the subdomain and IP address (or host), save or update the record. This action varies depending on your DNS management console, but it's typically labeled as "Save," "Update," or similar.
8. **Wait for DNS Propagation:**
- DNS changes may take some time to propagate across the internet. This process can take anywhere from a few minutes to 48 hours, although it's usually faster.
9. **Verify the Changes:**
- After some time has passed, you can verify if the subdomain is now pointing to the new IP address or host. You can use online DNS lookup tools to check the A record for your subdomain.
Keep in mind that changes to DNS records can affect website accessibility and email delivery. Always make sure you're making changes with caution, and double-check your configurations before saving.
