World of Computer Networking Your CCNA start - Private Internet Protocol (IP) Addresses

The video tutorial covers routing and subnetting, focusing on route aggregation and private IP addresses as defined by RFC 1918. It explains how route aggregation can simplify network management by combining multiple smaller networks into larger ones. The tutorial also discusses the importance of aggregated routes in filtering private IP addresses and their role in routing protocols. Finally, it introduces the concept of autonomous systems in the context of IGP and EGP protocols.

What document defines the ranges for private IP addresses?

• RFC 1234

• RFC 2020

• RFC 5678

• RFC 1918

How many Class B networks can be combined into one aggregated network?

• 32

• 8

• 16

• 64

What is the new mask when 256 Class C networks are aggregated?

• 16

• 8

• 24

• 12

Why are private IP addresses not routable on the global Internet?

• They are too expensive to route.

• They are reserved for local networks.

• They require special hardware.

• They are too slow for global routing.

What is the role of backbone routers in the Internet?

• To provide wireless connectivity

• To route only public IP addresses

• To manage local area networks

• To route only private IP addresses
