How to Network • Internet Protocol version 6 (IPv6) • Packets • Dynamic Host Conﬁguration Protocol (DHCP) • Wi-Fi

Slide 23

Slide 23 text

Internet Protocol version 6 (IPv6) • Every device on the Internet is assigned an IP address for identiﬁcation & location deﬁnition • Proposed in 1998 by Internet Engineering Task Force (IETF) • Successor to IPv4 • Uses 128-bit address (instead of 32)

Slide 24

Slide 24 text

Packets • the basic unit of transport for digital communications networks • A sequence of bytes (1's and 0's) that contain a source address, destination address, and body • headers === metadata, i.e. sender/receiver address • body === the information the sender wants the receiver to have, must be less than 64KB

Dynamic Host Conﬁguration Protocol (DHCP) • Protocol for dynamically assigning IP addresses • Used to control the network conﬁguration of a host through a remote server • Consists of various message types, i.e. DHCPDISCOVER, DHCPOFFER, DHCPREQUEST • the IP address assigned by server to client is on a lease

Slide 27

Slide 27 text

Wi-Fi / WiFi • Any "wireless local area network" (WLAN) product based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards • Less secure than wired connections • First version of the 802.11 protocol was released in 1997 • Suggested method of security is WPA2
