Domain Registration and DNS Migration with Amazon Route 53 - Registrar Transfers and Zone Configuration
A comprehensive walkthrough covering domain registration, transfers from other registrars, public and private hosted zone design, and enabling DNSSEC.
Registering a Domain with Route 53
Route 53 also functions as a domain registrar, allowing you to register domains directly from the console. It supports hundreds of TLDs including .com ($13/year), .net ($11/year), and .jp ($99/year). When you register a domain, a public hosted zone is automatically created with NS and SOA records. WHOIS privacy protection is available at no extra cost for supported TLDs, preventing your personal information from being publicly exposed. Enabling auto-renewal helps prevent accidental domain expiration.
Transferring from Another Registrar
Transferring an existing domain from another registrar to Route 53 involves three steps: disable the Transfer Lock at your current registrar, obtain the authorization code (Auth Code / EPP Code), and submit a transfer request through the Route 53 console. Transfers typically take 5-7 days to complete. Creating a hosted zone in Route 53 and replicating your existing DNS records before the transfer prevents DNS resolution interruptions during the process. After the transfer completes, the name servers automatically switch to Route 53. Transferring .jp domains requires additional JPRS procedures and an approval process at the source registrar.
Hosted Zone Design and DNSSEC
Public hosted zones respond to DNS queries from the internet, while private hosted zones respond only to queries from within designated VPCs. A common pattern is to manage a domain like internal.example.com in a private hosted zone for service-to-service communication within a VPC using domain names. DNSSEC adds digital signatures to DNS responses to detect tampering. In Route 53, signing keys are managed with KMS customer-managed keys, and DNSSEC signing can be enabled from the console. After enabling it, you register a DS record with the parent zone (the TLD registry) to complete the chain of trust. To broaden your knowledge of network design, specialized books on Amazon can be a helpful resource.
Route 53 Pricing
Domain registration is charged annually per TLD: .com is $13, .net is $11, and .jp is $99. Hosted zones cost $0.50 per zone per month, and DNS queries are $0.40 per million for the first 1 billion queries per month. Queries to alias records are free, reducing costs when routing to CloudFront or ALB. DNSSEC signing incurs no additional charge, but the KMS key costs $1 per month. Health checks cost $0.50 per check per month for AWS endpoints or $0.75 for non-AWS endpoints.
Summary
Route 53 is a service that unifies domain registration and DNS management. Transferring from other registrars strengthens integration with the AWS ecosystem, and DNSSEC improves DNS trustworthiness. By using public and private hosted zones appropriately, you can manage both external and internal DNS in a unified manner.
