What is my IP address?

Multiple command line HTTP clients are supported, including curl, httpie, GNU Wget and fetch.

CLI examples:

$ curl v4.ifconfig.co

$ http -b v4.ifconfig.co

$ wget -qO- v4.ifconfig.co

$ fetch -qo- https://v4.ifconfig.co

$ bat -print=b v4.ifconfig.co/ip

Country lookup:

$ http v4.ifconfig.co/country
United States

City lookup:

$ http v4.ifconfig.co/city

JSON output:

$ http v4.ifconfig.co/json
    "city": "Ashburn",
    "country": "United States",
    "hostname": "ec2-54-234-45-10.compute-1.amazonaws.com",
    "ip": "",
    "ip_decimal": 921316618

Setting the Accept header to application/json also works.

Plain output:

Always returns the IP address including a trailing newline, regardless of user agent.

$ http v4.ifconfig.co/ip

Testing port connectivity:

$ http v4.ifconfig.co/port/8080
    "ip": "",
    "port": 8080,
    "reachable": false


How do I force IPv4 or IPv6 lookup?

IPv4 or IPv6 lookup can be forced by using the v4 and v6 subdomains.

Is using this service from automated scripts/tools permitted?

Yes, as long as the rate limit is respected. Please limit automated requests to 1 request per minute. No guarantee is made for requests that exceed this limit. They may be rate-limited (with a 429 response code) or dropped entirely.

Can I run my own service?

Yes, the source code and documentation is available on GitHub.
