IP Addresses

Knowing the IP addresses of the build machines Travis CI uses can be helpful when you need them safelisted to access your internal resources. Since builds run in a variety of different infrastructures, the IP ranges to safelist depend on the infrastructure your builds are running on:

Infrastructure IP ranges
Container-based (travis-ci.com) workers-nat-com-shared-2.aws-us-east-1.travisci.net (,,,
Container-based (travis-ci.org) workers-nat-org-shared-2.aws-us-east-1.travisci.net (,,,
Sudo-enabled Linux See notes below (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Note: We do not have static public IP addresses available for jobs running on the sudo-enabled Linux infrastructure at this time.

This list of IP addresses is obtained by the process described by Google. We recommend using one of the other infrastructures if you need static IP addresses.

Note that these ranges can change in the future, and that the IP addresses used for notifications are different.

More details about our different infrastructures are available on the virtualization environments page.
