- Subdomains: Hundreds of numbered subdomains (n1 through n327+) distribute load across authentication servers
- DNS Hosting: AWS Route 53 with four geographically distributed nameservers
- Mail Server: mail.network-auth.com (priority 10)
- SSL Validation: IdenTrust certificate validation configured
