Questions and Answers

What is the main purpose of using Network Address Translation (NAT) in the context of IPv4 address exhaustion?

  • To allocate new public IP addresses
  • To eliminate the need for private IP addresses
  • To increase the number of available devices by allowing them to share a single public IP address (correct)
  • To provide encryption for data communication

    • What is the primary function of Source Network Address Translation (SNAT) and Port Address Translation (PAT)?

  • Modify both the IP address and port number for translation purposes (correct)
  • Modify the domain name of the devices
  • Change the private IP address to a public IP address
  • Allocate new private IP addresses for devices

    • What is the significance of the IP address ranges 10.0.0.0-10.255.255.255, 172.16.0.0-172.31.255.255, 192.168.0.0-192.168.255.255?

  • They are reserved for public IP addresses
  • They are assigned to devices without the need for translation
  • They are used exclusively for SNAT purposes
  • They are defined as private IP addresses in RFC 1918 (correct)

    • How does NAT enable devices with private IP addresses to communicate with devices on the public internet?

    Study Notes

    • Over 20 billion devices on the internet, but IPv4 only supports 4.29 billion addresses
    • IPv4 address space exhausted, no easy way to obtain new public IP addresses
    • Use Network Address Translation (NAT) to increase number of available devices
    • Private IP addresses defined in RFC 1918: 10.0.0.0-10.255.255.255, 172.16.0.0-172.31.255.255, 192.168.0.0-192.168.255.255
    • NAT allows devices with private IP addresses to communicate with public addresses
    • Router provides translation functionality by changing private source IP to public IP
    • When information is sent back to a private address, router reverses IP translation
    • NAT can handle multiple IP addresses by using Source Network Address Translation (SNAT), Port Address Translation (PAT), or NAT overload
    • SNAT/PAT: router modifies both IP address and port number to make translation
    • Router creates table to map private IP and public IP/port combination
    • When Professor Messer web server sends information back, router looks up mapping and sends traffic to correct private IP address.
