Use curl for automation
Add nossl.sh to shell scripts to record the IP each job uses when running from VPNs, CI/CD, or edge nodes.
Choose the plain-text or JSON endpoints depending on what your tooling needs.
- Plain text IPv4: curl http://nossl.sh
- Plain text IPv6: curl http://v6.nossl.sh
- JSON with headers: curl -H "Accept: application/json" http://nossl.sh/api/request-info
Validate dual-stack egress
Paired IPv4 and IPv6 endpoints confirm which path your traffic takes and make it easy to share with network teams.
- Useful for NAT64/464XLAT and tunnel troubleshooting.
- Refresh to capture a new timestamp before filing tickets.
What does the response look like?
The root endpoints return only the IP and a newline, making them safe for shell parsing. The API endpoint returns structured JSON.
Is there a rate limit?
nossl.sh is intended for lightweight diagnostics; reasonable automation is fine, but avoid high-frequency scraping.
