CLI Tools / API

Check any IP from your terminal with curl — no browser needed. CLI/script requests to this site get plain text automatically (browsers still get the web page).

curl quickref

curl ipyou.netyour IP details (plain text)

curl ipyou.net/ipjust the IP — ideal for scripts

curl ipyou.net/1.1.1.1look up a specific IP

curl ipyou.net/myipsame as curl to the site root

JSON API (for scripts / apps)

curl ipyou.net/api/v1/details/1.1.1.1full JSON for a given IP

curl ipyou.net/api/v1/myip/detailsfull JSON for your own IP

Script examples

# store your public IP in a variable
MYIP=$(curl -s ipyou.net/ip)

# refresh your IP every 5s (watch egress changes)
watch -n5 "curl -s ipyou.net/ip"

Note: Plain-text / bare-IP endpoints are never cached, so switching network / proxy returns fresh results instantly; JSON details are cached per IP for speed.
