I am trying to map subdomain to amazon ec2 with elastic IP. I already mapped the www.xxxexample.com to my shared hosting by giving the dns server name (ns1.justhost.com). And I created a many subdomains using the cpanel of shared hosting. Shared hosting is working fine. Amazon route53 is a paid service. So I dont want to use that service. I want to map my subdomain points to amazon ec2 instance and main domain already primarily mapped to shared hosting. I tried from the below example, nothing worked for me, getting my domain name to point to my amazon ec2 instance Can anybody help me to get rid of this issue?? Thanks in advance.
