What is my IP address? — ifconfig.name

CLI examples

$ curl ifconfig.name
3.236.122.9

$ http -b ifconfig.name
3.236.122.9

$ wget -qO- ifconfig.name
3.236.122.9

$ fetch -qo- https://ifconfig.name
3.236.122.9

$ bat -print=b ifconfig.name/ip
3.236.122.9

JSON output

$ http ifconfig.name/json
{
  "ip": "3.236.122.9",
  "ip_decimal": 65829385,
  "hostname": "ec2-3-236-122-9.compute-1.amazonaws.com",
  "user_agent": {
    "product": "CCBot",
    "version": "2.0",
    "comment": "(https://commoncrawl.org/faq/)",
    "raw_value": "CCBot/2.0 (https://commoncrawl.org/faq/)"
  }
}

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.
