⁠cidrtools

CIDR Tools is an app to assist in network address planning/design. I wanted to learn the basics of writing a python-based web application and at the same time have a simple tool to use. This application has the following functions:

• Disector - this takes any IPv4 address in CIDR form and shows details about it
• Subnet - is used to break up a parent network into subnets based on a new desired prefix length
• Supernet - is to show what parent networks a subnet belongs to
• Summary - given a list of hosts and/or networks, produce the summary prefix(s)
• Splitnet (in progress) - show the prefix summaries after splitting up a prefix

The results are provided in an HTML table, so data is easily cut/paste into a spreadsheet or other forms of documentation.
