When the device sends out an IP packet, if the destination is not on the same network, the device has to send the packet to its default gateway, which will then send it out toward the destination. DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives every computer on your home network an IP address.
cascaded decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything from 000 to 255, or as four cascaded binary numbers separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1. A network mask is also a 32-bit binary pattern, and consists of consecutive leading 1’s followed by consecutive trailing 0’s, such as 11111111.11111111.11111111.00000000. Therefore, sometimes a network mask can also be described simply as “x” number of leading 1’s.
