What is my IP address?

CLI examples

$ curl my4ip.omnilance.com
3.144.40.78

$ http -b my4ip.omnilance.com
3.144.40.78

$ wget -qO- my4ip.omnilance.com
3.144.40.78

$ fetch -qo- https://my4ip.omnilance.com
3.144.40.78

$ bat -print=b my4ip.omnilance.com/ip
3.144.40.78

JSON output

$ http my4ip.omnilance.com/json
{
  "ip": "3.144.40.78",
  "ip_decimal": 59779150
}

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

FAQ

How do I force IPv4 or IPv6 lookup?

As of 2018-07-25 it's no longer possible to force protocol using the v4 and v6 subdomains. IPv4 or IPv6 still can be forced by passing the appropiate flag to your client, e.g curl -4 or curl -6.

Is automated use of this service permitted?

Yes, as long as the rate limit is respected. The rate limit is in place to ensure a fair service for all.

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 status code, or dropped entirely.

Can I run my own service?

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