4. Understanding the TCP/IP Protocol Suite
Set of rules formalized in a standard
Protocols define software used in networking
Software must work together
Software bundled together in a protocol stack
TCP/IP is the most important protocol stack

5. The TCP/IP Protocol Suite
Suite of many protocols that work together
Protocol suite of the Internet and private networks
Two core protocols
Transmission Control Protocol (TCP)
Internet Protocol (IP)

6. Transmission Control Protocol (TCP)
Manages accurate delivery of messages
Verifies and resends pieces that fail to reach destination
TCP has several subprotocols

7. Why IPv6 is Better than IPv4
IPv6 has many more addresses
Has Mobile IP for mobile devices
Automatically assigns addresses to devices
Manages addresses better than IPv4
Subprotocols provide better security

8. IP Addressing Fundamentals
IP address assigned to a network adapter
Modem (cable, DSL, or analog) has address
Subnet mask applied to IP address
Routing protocols determine how to send packets
Globally unique IP address for each Internet device

9. Windows 10 Ethernet Properties Dialog Box

10. IPv4 Addresses In use for three decades 32-bit addressing (232)
4.3 billion possible IP addresses
Allocation methods reduced usable addresses
Four parts in dotted-decimal format ( )
Each part is within 0 to 255 range
Last IPv4 block assigned on February 1, 2011

Connects via router to WAN to ISP to Internet
Newer standards faster and more secure

33. Using a Virtual Private Network (VPN)
A simulated private network inside a “tunnel”
Connect to a remote access VPN
Site-to-site VPN
Each data packet encapsulated
Secure by encrypting data before encapsulating
Secure with authentication at both ends
