We will be enabling IPv6 support for Buildkite's APIs on 2024-09-18. This includes api.buildkite.com, graphql.buildkite.com, and analytics-api.buildkite.com. If you have any clients consuming the Buildkite API while operating on a dual-stack network, it is important to check that any API Token IP allowlists, and any Organization API IP allowlists permit your IPv6 network ranges in preparation for the change.
