# Azure Services - DNS Suffix

## DNS table

Many Azure services generate custom endpoints with a suffix such as `.cloudapp.azure.com`, `.windows.net`. Below is a table of common services and their associated DNS suffixes.

These services can also be leveraged for domain fronting or communication with an external C2 server when they are whitelisted by the proxy or the firewall rules.
