Understanding Internet Protocol Lesson 4

  1. These are addresses assigned to a group of interfaces, most likely on separate hosts. Packets that are sent to these addresses are delivered to only one of the interfaces—generally, the first one, or closest, available. These addresses are used infailover systems.
    Anycast address
  2. is the most frequently used communications protocol.
    Internet Protocol version 4 or IPv4
  3. The IPv4 classification system is known as the
    classful network architecture
  4. are used by the government, ISPs, big corporations, and large universities.
    Class A network addresses
  5. are used by mid-sized companies and smaller ISPs.
    Class B network addresses
  6. are used by small offices and home offices.
    Class C network addresses
  7. is synonymous with “host.”
  8. which is used to communicate with all hosts on the network.
    broadcast address
  9. transmitting data to multiple computers (or routers).
  10. Another type of private range was developed by Microsoft for use on small peer-to-peerWindows networks. It is called
    APIPA, which is an acronym for Automatic Private IPAddressing
  11. is the first IP address of the device that a client computer will look for when attempting to gain access outside the local network.
    default gateway
  12. is the IP address of the device or server that resolves DNS addresses to IP addresses.
    DNS server address
  13. is the process of modifying an IP address while it is in transit across a router, computer, or similar device.
    Network address translation (NAT)
  14. a subset of NAT, which translates both IP addresses and port numbers.
    port address translation (PAT),
  15. is the act of dividing a network into smaller logical subnetworks.
  16. is a way of allocating IP addresses and routing Internet Protocol packets.
    Classless inter-domain routing (CIDR)
  17. which allows a network to be dividedinto different-sized subnets to make one IP network that would have previously been considereda class (such as Class A) look like Class B or Class C.
    variable-length subnet masking (VLSM)
  18. is the new generation of IP addressing for the Internet, but it can also be used insmall office networks and home networks. It was designed to overcome the limitations ofIPv4, including address space and security.
  19. This is a single address on a single interface.
    Unicast address
  20. These addresses are also assigned to a group of interfaces and are also most likely on separate hosts, but packets sent to such an address are delivered to all of the interfaces in the group.
    Multicast address:
  21. This is the first three groups of numbers, and it defines the “network”of the address.
    Global routing prefix
  22. This defines the individual subnet of the network that the address is located on.
    IPv6 subnet
  23. This is the individual host IP portion. It can be assigned to one interfaceor more than one interface, depending on the type of IPv6 address.
    Interface ID
  24. exists when there are two Internet Protocol software implementations in anoperating system, one for IPv4 and another for IPv6.
    dual IP stack
  25. have the first 80 bits set to 0 (note the double colon), the next 16set to 1 (shown as ffff ), and the last 32 bits populated by the IPv4 address.
    IPv4-mapped addresses
  26. IPv6 packets can be encapsulated inside IPv4 datagrams. This is known as
    IPv6 tunneling,
