Quay.io
Red Hat's public registry. Hosts most OpenShift platform images and many open source projects.
| Host | Ports | Purpose | |
|---|---|---|---|
| quay.io | 443 | Registry API and token authentication | required |
| cdn.quay.io | 80 443 | Blob CDN (redirect target) | required |
| cdn01.quay.io | 80 443 | Blob CDN (redirect target) | required |
| cdn02.quay.io | 80 443 | Blob CDN (redirect target) | required |
| cdn03.quay.io | 80 443 | Blob CDN (redirect target) | required |
| cdn04.quay.io | 80 443 | Blob CDN (redirect target, added 2025) | required |
| cdn05.quay.io | 80 443 | Blob CDN (redirect target, added 2025) | required |
| cdn06.quay.io | 80 443 | Blob CDN (redirect target, added 2025) | required |
Notes
Blob content cannot be fetched from the CDN hosts directly - the registry issues short-lived signed redirect URLs. Open the hostnames, do not try to pin IP addresses.
