Netmask

ipcalc project takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as...

IPlib is a Python module to convert between many different IP address notations and to manage netmask/address pairs in the CIDR notation. Some example scripts ("ipconv", "nmconv", and "cidrinfo") are included..

ICMPInfo is a tool that uses ICMP type 13 and 17 to retrieve the current time of a remote host and its netmask.. Luigi Auriemma
