IPlib 0.9 can be downloaded from: http://erlug.linux.it/~da/soft/iplib/ IPlib is a Python module useful to convert amongst many different notations and to manage couples of address/netmask in the CIDR notation. Some example scripts ('ipconv', 'nmconv' and 'cidrinfo') are included. With this release, you can use the CIDR class to test if a CIDR net is entirely contained in another one. -- Davide Alberani <alberanid@libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/
