Subnet Mask Cheat Sheet. See also RFC 1878.
Check this out. A trick we used to do back in the web hosting biz was to use the entire subnet when assigning
IP mask numbers are used to divide internet addresses into blocks called subnets. The mask number represents the number of 1s in the binary of the address that is 'masked" against the address so that it ignores the last bits which are for the group of IP addresses in the masked address.
Subnet mask calculator. With subnet mask you can split your network into subnets. Enter your IP address and play with the second netmask until the result matches your need.
A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into multiple subnetworks is called subnetting. Computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address.
The subnet calculator lets you enter a subnet range (CIDR) and see IP address information about that range.

Currently, we have a /29 block of static IPs for our network, usable range .9-.14. Currently, our single gateway is set as Gateway on .9, subnet 255.255.255.248 and NAT on .10.
Is there a command line based way to send pings to each computer in a subnet?
Like you said, a /29 leaves 3 bits for addresses. However, the first address is the network address and cannot be used for a host.
