IP address tools in Javascript

In my earlier blog I put a set of tools together for IPv4 address manipulation for sqlite,oracle and even Excel. How can I forget the simple tools needed in Javascript.  Changing IP address to long integer, subnet mask to IP address range, have all become a necessity to daily security operations people.  So here is what I have cooked up.

Ever stuck with having to do data manipulation in Excel at a customer's restricted Microsoft environment, say with IP Addresses?  Here are some time savers for your IPV4 address manipulation in Microsoft Excel.  I have also added some SQLite function which can be helpful as SQLite has no native INET_NTOA or INET_ATON functions in MySQL.
