Dynamic IP Address
A dynamic IP address is a temporary IP number, dynamically or randomly generated by a
DHCP server. The address lasts only as long as the server allots, usually in the space of a
day or two. When the IP address expires, the client is automatically reassigned a new IP
address, ensuring smooth communication.
If you are using your wireless router to share an Internet connection, your ISP might have
assigned you a dynamic IP address, which you use when configuring your router. See
Section 3: Configuration.
DHCP Server
A Dynamic Host Configuration Protocol (DHCP) Server assigns IP addresses to clients
connected to the router. A client is any device that can connect with your router. The client
(PC, gaming device, etc.) is automatically assigned an IP address every time a device is
added to your network, which frees you from manually assigning IP addresses.
Sample Home Network Diagram
Your wireless router serves as the centerpiece of your network, allowing you to share files,
printers, and the Internet connection. A sample home network is shown below:
The Internet communicates with the modem, which in turn communicates with the router.
The router acts as the gateway to your network; it sends devices information such as
requests for Internet access, file sharing, or multiplayer games. The router controls the
information for your network, intelligently routing the information to its required destination
while at the same time protecting your network from the public domain.
