IPy

IPy is a Python class and suite of tools designed to efficiently manage IPv4 and IPv6 addresses and networks. This program is very reminiscent of the Net::IP Perl module. The IP class provides a seamless parsing and handling experience across various notations commonly used for IPv4 and IPv6 Addresses and Networks. The inspiration for this program was drawn from RIPE's Perl module NET::IP's interface but with an entirely unique implementation. However, IPy does not share non-CIDR netmasks, so complex structures like a netmask of 0xffffff0f cannot be used.

Using IPy is incredibly simple; from IPy import IP and you're ready to start. With just one line, an IP can be initialized and parsed; for example, IP('127.0.0.0/30'). A loop statement can be then be written to iterate through the various IP addresses, as seen in the sample code provided. ReverseName and reverseNames can also be run on this IP, generating the corresponding DNS-entries that match the IP's address range. Finally, IPTYPE allows us to determine whether or not the IP is a private address.

Overall, IPy has proven to be an incredibly efficient and useful tool for managing IP addresses and networks in Python. Its ease-of-use, combined with its vast range of functionalities, has earned IPy a coveted place in most software developer's portfolio.
