A Private Hosted Zone in Route 53 is a container for DNS records that are only accessible from within one or more VPCs. This allows you to manage DNS names for resources in your VPCs, such as EC2 instances, databases, and load balancers, without making these DNS records available to the public.
A Private Hosted Zone in Amazon Route 53 is a DNS zone that is used to manage DNS records within your Amazon Virtual Private Cloud (VPC). Unlike a public hosted zone, which handles DNS records visible to the public internet, a private hosted zone is used solely within one or more VPCs. It allows you to create and manage DNS records that are only resolvable within your VPC. This means that only resources within the associated VPCs can use these DNS records. Private hosted zones are ideal for internal DNS management, providing a way to manage domain names for resources that do not need to be accessible from the internet.
