Jul 17, 2005 · What's a netmask? All devices on a local network have a unique IP address, but each address is inherently divided into two parts, a shared network part, and a unique host part, and this information is used by the TCP/IP stack

How to Understand IP Address and Subnet Mask? | FS Community TCP/IP (Internet Protocol) is a suite of communication protocols used to interconnect network devices (router, 10gbe switch and etc) on the internet. And an IP address, subnet mask and a default gateway are necessities in the TCP/IP configuration. IP Calculator / IP Subnetting ipcalc 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 easy-to-understand binary values.
