Enterprise Domain Name System (DNS) Delegation & Subdomain Architecture
Architected enterprise DNS subdomain delegation to allow isolated management of departmental and cloud application DNS records.
Key Features & Implementation
- Subdomain NS Delegation: Delegated subdomains (e.g., app.domain.com) to dedicated cloud DNS name servers using explicit NS records.
- Glue Record Registration: Configured glue records at domain registrars to ensure seamless name resolution for delegated child name servers.
- Split-Brain Zone Alignment: Maintained internal DNS zone mirroring ensuring private IP resolution for internal network users.
