There is a default DNS resolver available for all VPCs at VPC+2 ip, resolving requests to local ec2 instances, public names servers, and for private host zones
Hybrid-DNS
- Resolving DNS queries across networks such as
- Peer to peer
- On prem S2S or DX
- Resolver endpoints
- Inbound endpoints - Forward from On prem/systems/privatehostedzones to your Route53 resolver
- Outbound endpoints - Forward to On Prem/systesm/privatehostedzone from your Route53 resolver
Helps removing the need to run your own Resolver on aws and link them to on premises
