You can use https://ip-api.io/ to get city Name. It supports IPv6.
The Geolocation API is accessed via a call to navigator. geolocation ; this will cause the user's browser to ask them for permission to access their location data. If they accept, then the browser will use the best available functionality on the device to access this information (for example, GPS).
You would do something like that using Google API.
Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.
"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.
Anyhow - more details on google response types can be found here and here.
Below is the code that should do the trick:
<!DOCTYPE html>

<script type="text/javascript">
var geocoder;
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(successFunction, errorFunction);
}
//Get the latitude and the longitude;
function successFunction(position) {
var lat = position.coords.latitude;
var lng = position.coords.longitude;
codeLatLng(lat, lng)
}
function errorFunction(){
alert("Geocoder failed");
}
function initialize() {
geocoder = new google.maps.Geocoder();
}
function codeLatLng(lat, lng) {
var latlng = new google.maps.LatLng(lat, lng);
geocoder.geocode({'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
console.log(results)
if (results[1]) {
//formatted address
alert(results[0].formatted_address)
//find country name
for (var i=0; i<results[0].address_components.length; i++) {
for (var b=0;b<results[0].address_components[i].types.length;b++) {
//there are different types that might hold a city admin_area_lvl_1 usually does in come cases looking for sublocality type will be more appropriate
if (results[0].address_components[i].types[b] == "administrative_area_level_1") {
//this is the object you are looking for
city= results[0].address_components[i];
break;
}
}
}
//city data
alert(city.short_name + " " + city.long_name)
} else {
alert("No results found");
}
} else {
alert("Geocoder failed due to: " + status);
}
});
}

<div>Latitude: <span id="latitude"></span></div>

<div>IP: <span id="ip"></span></div>Using html5 geolocation requires user permission. In case you don't want this, go for an external locator like https://geolocation-db.com IPv6 is supported. No restrictions and unlimited requests allowed.
Example
For a pure javascript example, without using jQuery, check out this answer.
Another approach to this is to use my service, http://ipinfo.io, which returns the city, region and country name based on the user's current IP address. Here's a simple example:
$.get("http://ipinfo.io", function(response) {
console.log(response.city, response.country);
}, "jsonp");
Here's a more detailed JSFiddle example that also prints out the full response information, so you can see all of the available details: http://jsfiddle.net/zK5FN/2/
You can get the name of the city, country, street name and other geodata using the Google Maps Geocoding API
