IPCache is a simple Firefox Add-on to cache IP addresses of websites that you visit. If DNS goes down across the internet, IPCache can then be used to access cached sites that you have visited via IP address. Think of it as your "Internet On Switch".
IPCache is released under the Mozilla Public License.
Install IPCache [ November 10, 2011]
After installing IPCache, there is nothing else you need to do. All websites you visit will be logged in your Bookmarks Menu folder under the newly created IPCache folder. If you click on any of the bookmarked items in the IPCache folder, you can then visit the website via IP address.
