have Problem with my domain regarding my Wordpress WEBSITE

When I am trying to open my website from my PC then I get below IP address , which is not mine . I neither use Proxy nor any tools . The message is displayed as below.

Your computer IP address 108.162.222.234 is listed at StopForumSpam database so your visit is blocked. You can unblock yourself by entering the following code:

---Captcha code is given here---

when I entered Right captcha of Image then It says "You have entered invalid captcha" and doesn't proceed ahead.

SO I want to know that somebody is trying Hacking or something else with my website ?
