How to get client’s IP address using JavaScript?
There’s no built-in solution in JavaScript to get IP Address of the client’s server but there are other cool ways. Using public APIs that returns IP Address is one of the ways (and my favourite too). We can call a publicly available API without any need of additional libraries to fetch IP Address.

const url = "https://api.ipify.org/?format=json"
fetch(url)
.then(response => response.json())
.then(data => console.log(data));
//{"ip":"106.201.178.230"}Here I use fetch API to retrieve a publicly available HTTP API from Ipify that returns IP Address of the client machine. You can use Axios if you are developing a backend service and you need to find IP address.
Ipinfo’s API returns a lot more details like City, ISP, Country, Zipcode etc.
const url = "https://ipinfo.io/json"
fetch(url)
.then(response => response.json())
.then(data => console.log(JSON.stringify(data)));
/*
{
"ip": "106.206.78.230",
"city": "Bengaluru",
"region": "Karnataka",
"country": "IN",
"loc": "12.9719,77.5937",
"org": "AS45609 Bharti Airtel Ltd. AS for GPRS Service",
"postal": "560002",
"timezone": "Asia/Kolkata",

Using a external library is another way but I don’t recommend it. Here I use Ipinfo’s JS library to get IP address.
<script type="application/javascript">
function getip(json){
alert(json.ip);
}
</script>
<script type="application/javascript" src="http://ipinfo.io/?format=jsonp&callback=showIP"></script>
