One-line commands to copy
Use curl http://nossl.sh for IPv4 and curl http://v6.nossl.sh for IPv6. Each responds with just the address and a trailing newline.
Need more detail? Hit /api/request-info with curl to get JSON headers alongside your IP.
- curl http://nossl.sh
- curl http://v6.nossl.sh
- curl -H "Accept: application/json" http://nossl.sh/api/request-info
Why use this over ifconfig-style sites
nossl.sh is intentionally plain HTTP so captive portals do not block it, while still exposing both public IP addresses.
- Lightweight response ideal for cron and scripts.
- Dual-stack coverage with matching endpoints.
- Shareable report if you need UI context later.
Does the curl output include IPv6?
Use the v6 endpoint for IPv6-only output; the main host stays on IPv4 so there is no ambiguity.
Can I force HTTPS instead?
HTTPS is available, but the HTTP endpoints avoid captive portal issues and keep the commands shorter.
