Messer Chapter 2.3 - An overview of IPv4 and IPv6

  1. IPv4
    Internet Protocol Version 4
  2. What does each number in an IP address represent?
    • 192.168.1.131
    • (192 = 8 bits because it's in binary)
  3. What is the max number you can have in an IP address?
    255
  4. What is the range of binary for IP address ?
    from 1-128
  5. How many bits are in an IPv4 address?
    32 bit
  6. How many bits is an IPv6 address?
    128 bit address
  7. How is IPv6 represented?
    • In hexadecimal
    • EX - fe80::5d18:652:cffd:8f52
  8. What do you call the first 64 bits to the left side of an IPv6 address?
    Network address
  9. What do you call the last 64 bits to the left side of an IPv6 address?
    Host IPs
  10. What 2 things can you do to make an IPv6 address smaller so they are easier to read?
    • 1. Remove leading zeros
    • EX - fe80:0000:0000:0000:cabc:c800:00a7:08d5
    • fe80:0:0:0:cabc:c800:a7:8d5
    • 2. Abbreviate 2+ groups of zeros with double colons
    • fe80::cabc:c800:a7:8d5
  11. What is an APIPA address?
    When a DHCP server is unavailable, APIPA assigns a class B IP address
  12. What does an link local address start with in an IPv6 address?
    fe80 and a bunch of zeros
  13. What is the subnet mask?
    It lets the local workstation know what network it belongs to
  14. What are the 3 ingredients for addressing?
    • 1. IP address
    • 2. Subnet mask
    • 3. Default gateway
  15. What is a default gateway?
    an IP address thats connected to your modem/router
  16. DHCP
    Dynamic Host Configuration Protocol
  17. What is DHCP?
    Automates the IP address configuration
  18. CIDR
    Classless Inter-Domain Routing
  19. What is CIDR?
    Expressing subnet masks as a slash and a number.

    EX - 255.0.0.0/8 <- Bits


  20. Explain
  21. What is the IP address range for APIPA?
    169.254.1.0 through 169.254.254.255
  22. What are the last 64 bits created with in a IPv6 Link Local Address?
    a modified EUI-64
  23. What is a class A ip address ?
    10.0.0.0 0 - 10.255.255.255
  24. What is a class B ip address ?
    172.16.0.0 - 172.31.255.255
  25. What is a class C ip address ?
    192.168.0.0 - 192.168.255.255
  26. What is RFC 1918?
    Private address


  27. Explain hosts and network address bits
  28. What is a static IP?
    An address that does not change which is typed in manually
  29. What is a dynamic IP?
    Are assigned by the network and change over time
  30. DNS
    Domain Name Server
  31. What does the DNS do?
    Converts domain names to IP addresses
