How to get client's IP address using JavaScript?

javascript jquery ip-address
FlySwat picture FlySwat · Dec 24, 2008 · Viewed 1.2M times · Source

I need to somehow retrieve the client's IP address using JavaScript; no server side code, not even SSI.

However, I'm not against using a free 3rd party script/service.

I would use a web service that can return JSON (along with jQuery to make things simpler). Below are all the free active IP lookup services I could find and the information they return. If you know of any more, then please add a comment and I'll update this answer.

});

Returns:

  "ip": "116.12.250.1"
}

Limitations:

  • No SSL (https)
  • Goes down a lot (over quota), so I wouldn't use it for production

    "longitude": 103.8565,
    "time_zone": "Asia/Singapore"
  },
  "ip": "116.12.250.1"
}

Limitations:

  • Blocked by ad blockers using the EasyPrivacy list

Keep in mind that since these are all free services, your mileage may vary in terms of exceeding quota and uptime, and who knows when/if they will be taken offline down the road (exhibit A: Telize). Most of these services also offer a paid tier in case you want more features like SSL support.

Also, as skobaljic noted in the comments below, the request quotas are mostly academic since this is happening client-side and most end users will never exceed the quota.
