www.bhutanmajestictravels.com is not viewable here in delhi too, stupid guy who dont know what he is loosing by blocking these IP if thats the case indeed.
Bhutan does not have its own ISP having its own trunk cable, so your ISP is using a leased line from another in the sub continent, may be singtel of singapore which covers the entire asia pacific region, hence all the user in that area range will get blocked, including me here in delhi.
IP blocking can be done from your cPanel, ask you host, you dont need anycode for doing this.
Strange that you are a webmaster & have not yet understood the concept of web.
Its a platform for free exchange of info, if you don't want anyone to copy then don't publish the site on the web, just have it on you computer only.
You block the bhutan IP & it can be surfed using free proxy server if I know the url (in this case mostly people will know)
Blocking bhutan IP means that you included & other who need info within bhutan & visit the site cannot do it.
Wake up & be realistic about the web & learn to use it to you advantage, best is to watermark the images with your site url, & text can be embedded within image /flash/applet etc..............but remember if it can be seen it can be copied too.
Bhutan may have copyright laws, deal with them & file complaint against others if you thing so.
