How can I resolve a custom domain name from resources in my VPC without modifying the DHCP options set?

Resolution

To configure a private hosted zone to specify how Amazon Route 53 responds to DNS queries for domains within your VPCs, do the following:

1. Create a private hosted zone for your domain name and attach it to the required VPC.
2. Create records in the private hosted zone to specify how Route 53 responds to DNS queries from resources in the attached VPC.
3. (Optional) Associate a Route 53 private hosted zone with a VPC on a different AWS account.
