curl -x "http://203.0.113.10:8080" https://api.ipify.org2. SOCKS5 with remote DNS
curl --socks5-hostname 203.0.113.10:1080 https://api.ipify.org3. SOCKS4
curl --socks4 203.0.113.10:1080 https://api.ipify.org4. Take the first proxy from the list
proxy="$(curl -sL https://raw.githubusercontent.com/xyzs996/free-proxy-health-list/main/http.txt | head -n 1)"
curl -x "http://$proxy" --max-time 10 https://api.ipify.orgNotes that save time
Use --socks5-hostname rather than --socks5 so the proxy resolves the target hostname; the plain flag resolves locally and leaks the lookup. Always set --max-time, because a dead proxy otherwise stalls the command. Add -f if you want curl to exit non-zero on an HTTP error so a shell loop can move on.
