16 - Network Address Translation (NAT)

 1. NAT stands for 'Network After Transportation'

  FALSE

  TRUE

 2. The reason for having the NAT service is to preserve the limited number of public IP4 addresses we have around the world.

  FALSE

  TRUE

 3. In order to prevent a shortage of public IP4 addresses, network engineers developed the concept of private IP addresses and network address translation.

  FALSE

  TRUE

 4. There are two types of IP4 addresses - public and private. You need a ___________ IP address to go on the internet!

  binary

  hexadecimal

  public

  private

  DNS

  router

 7. Most homes have multiple devices that need access to the internet. These devices need a public IP address to connect to the internet.
Note: If we had a public IP address for every device in each home, we would have run out already of IPV4

  TRUE

  FALSE

 8. A solution to not using several public IP addresses for each device in the home, is to have our router assign each device ____________________ which is translated by NAT in the router when accessing the internet

  private IP addresses

  binary addresses

  public IP addresses

  NAT addresses

 9. NAT translates only public addresses to private addresses and not the other way around.

  TRUE

  FALSE

 10. It is likely that in the future we won't need NAT or private IP addresses. This is because of ______________

  the new Domain name server that is being built

  IPV6 (the new generation of IP addresses) which will allow us never to run out.

  the removal of routers and bringing in hubs instead.

  quantum mechanics which will remove the need for any IP addresses
