Google App Engine Hosting Domain
appspot.com is the default hosting domain for applications deployed on Google App Engine, Google Cloud's fully managed serverless platform for developing and hosting web applications at scale. When developers deploy an application to App Engine, it is automatically assigned a subdomain under appspot.com (e.g.,myproject.appspot.com).
Key Features of App Engine
- Serverless Architecture – No server management required; Google handles infrastructure
- Automatic Scaling – Capacity adjusts dynamically based on traffic demand
- Multi-Language Support – Python, Go, Java, Node.js, PHP, Ruby, and .NET
- Two Environments – Standard (pre-configured runtimes) and Flexible (custom containers)
DNS Infrastructure
The domain is hosted entirely on Google's infrastructure:
| Record Type | Details |
|---|---|
| Nameservers | ns1-4.google.com (AS15169) |
| IPv4 | Multiple IPs in 192.178.155.x range |
| IPv6 | 2607:f8b0:4004:c23::/64 |
| SPF | v=spf1 -all(no mail sent from this domain) |
| DNSSEC | Not signed |
App Engine was one of the first Platform-as-a-Service (PaaS) offerings when Google launched it in 2008, predating competitors like Heroku and AWS Elastic Beanstalk. Today it remains a core component of Google Cloud Platform, serving millions of applications worldwide.
