For the following hosts, * represents any string not containing a period.

  • sites.google.com:80/HTTP

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 Google Sites uses.
  • Techniques that Google Sites uses to connect to Google servers depend on the browser, browser version, networking 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.
