How to add a subdomain pointing to IP of EC2 instance in AWS where the domain is pointing to the IP of the machine of some other hosting provider?

Question

Here is the situation -

1. I have my domain name xyz.com purchased from godaddy which is pointing to the website IP hosted by wix.com. 2 nameservers provided are of wix.com i.e. - ns2.wixdns.net & ns3.wixdns.net.
2. I have another website which is hosted in AWS EC2 instance with some IP say XX:XX:XX:XX

I want to create a subdomain sub.xyz.com which should point to the IP(XX:XX:XX:XX) of my AWS EC2 instance without affecting the main domain pointing to the website created through wix.com.

Things I did, but did not work -

1. I tried to contact godaddy for this purpose but they said it has to be done through AWS
2. Tried to use subdomain option on godaddy and created a subdomain record for sub.xyz.com for the IP address of the EC2 instance
3. Checked on internet and got some articles stating use of Route 53 on AWS. I tried to create one hosted zone file with xyz.com domain name but it created 4 new nameservers. Then I created a record set for this using -

name = sub.xyz.com,

record type = A-IPv4 Address,

TTL=300,

Value = XX:XX:XX:XX (IP of EC2 instance),

Routing policy = Simple

Route 53 provided 4 new nameservers which I think if I update on godaddy then it will not point domain name xyz.com to the website hosted by wix.com

I do not have much knowledge about AWS and domain/subdomain routing.

Answer 1

Create sub.xyz.com A record in Wix DNS.

Answer 2

After trying and as commented by Dusan above, creating 'A' record for "sub.xyz.com" in WIX resolved the issue.
