Important notes
- The IP addresses that various domain names resolve to don’t necessarily fall within any given address range.
- Other Google properties may use the IP addresses that Drive uses.Google.com
- Techniques that Drive uses to connect to Google servers depend on the browser, browser version, network conditions, etc.
- Even if you don’t currently observe activity at the addresses listed above in a particular Google product there could be future activity.
- The Drive sync client supports all unauthenticated proxies that are configured by the operating system.
- The sync client supports the only DNS-based distribution of PAC files. PAC distribution over DHCP is not supported.
