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

$ http v4.ifconfig.co/country-iso

City lookup

$ http v4.ifconfig.co/city

JSON output

$ http v4.ifconfig.co/json
  "ip": "",
  "ip_decimal": 920457706,
  "country": "United States",
  "country_iso": "US",
  "city": "Ashburn",
  "hostname": "ec2-54-221-17-234.compute-1.amazonaws.com"

Setting the Accept: application/json header also works as expected.

Plain output

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

$ http v4.ifconfig.co/ip

Port testing

$ 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.

Can I run my own service?

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