Default Gateway (Router): Every non-router IP device needs to configure a default 
gateway’s IP address. 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 towards the destination. 
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives 
every computer on your home network an IP address. 
DNS Server IP Address: DNS stands for Domain Name...

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. 
When both are represented side by side in their binary forms, all bits in the IP address 
that correspond to 1’s in the network mask become part of the IP network address, and 
the remaining bits correspond to the host ID.

transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP 
performs proper error detection and error recovery, and thus is reliable. UDP on the 
other hand is not reliable. They both run on top of the IP (Internet Protocol), a 
network layer protocol. 
 
WAN: Wide Area Network. A network that connects computers located in 
geographically separate areas (e.g. different buildings, cities, countries). The Internet 
is a wide area network.
