//
//  about:  the firewall at my place of work likes to block certain websites, but many of these sites are accessible by their IP address.
//  So I find it useful to replace the domain name for inline images with the IP address.  Edit this script to work for your favorite sites.
//
//  Note:  you can often get the IP address of a website by using the ping command.  In Windows, goto Start:Run, and type "cmd".  At the
//  command line, type ping www.blockedsite.com, and you should see the IP address.


//var domainname = ['www.blockedsite.com','www.blockedsite2.com'...];  //array of domain names of blocked sites

var domainnames = ['www.bungie.net','www.kongregate.com'];  //array of domain names of blocked sites
var ipaddresses = ['65.59.234.97','65.74.171.4'];	//array of IP addresses of blocked sites
