A Wildcard Mask Table is a table used for subnetting. It indicates the number of mask bits and the corresponding wildcard mask value. A wildcard mask is a sequence of numbers that can be used to identify a range of IP addresses by specifying which bits should be matched when matching an IP address and which should not be matched. For example, a wildcard mask of 0.0.0.255 would result in any IP address beginning with 0.0.0 being matched.

A DSL modem router is a device used to provide a high–speed Internet connection. It combines the functions of a modem and a router in one device. It connects to your ISP (Internet Service Provider) using either a phone line or cable line and allows you to access the Internet through a single box. The router then acts as a bridge between your home network and the World Wide Web. With this, you can access the web, send emails and share files with other computers on the same network. It also provides you with Wi–Fi capability to extend the reach of your wireless network.
