
Define and describe the Internet architecture
model and various Internet protocols
Describe the purpose of RFCs
Explain the routing process
Compare and contrast RIP with OSPF
Describe port numbers and their functions
Explain IP addressing, address classes, default
subnet masks and the use of private IP
addresses

Internet Addressing
field1.
field2.field3.field4
Each field represents one byte of data
Subnet Mask



Distinguishes the network and host portions of an
IP address
Specifies whether a destination address is local or
remote
Network portion of an Internet address can be
determined using the TCP/IP ANDing function

Version 6 (IPv6)


Shortcomings of IPv4
• Limited address space
• Lack of security
• Speed problems
• Configuration problems
Strengths of IPv6
• More efficient and requires less administrative
overhead than IPv4
• Provides a practically unlimited number of IP
addresses
• Less dependent on routers
