Enable Cross-Peer DNS
Enable Cross-Peer DNS
In this section, you will enable Cross-peering DNS to allow EC2 - My VPC to query EC2 - HG VPC**’s public DNS and return the IP address private of the VPC EC2- HG VPC and the connection will then go through the AWS intranet.
If this feature is not enabled, the connection between EC2 instances of EC2 - My VPC when querying EC2’s public DNS - HC VPC will return the public IP address and the connection will then go through the Internet.
- Return to VPC Management Console

Select Peering Connections in the left sidebar.
- Then, tick VPC peering connection between the 2 VPCs we have created.
- Select Actions

- In the Edit DNS Settings page, check the two boxes next to Requester DNS resolution and Accepter DNS resolution.
- Click Save then Close. This will take a few minutes to execute.
- From EC2 - My VPC, try to ping Public DNS of EC2 - HG VPC, and we will ping successfully.
