   Pennawd 1: Hi, hello there. 267s · Speaker 1

   Hi, hello there. Welcome to designing IP addressing and selecting routing protocols. This video lecture begins with a discussion of the design of an IP address or IPB4 addressing scheme. It continues with an introduction to IPv6 or IPv6 and…

   Pennawd 2: Network size and IP addressing planning. 118s · Speaker 5

   Network size and IP addressing planning. So determining the size of the network. So the first step in designing an IP addressing plan is determining the size of the network to establish how many IP subnets and how many IP addresses are need…

3. 6:29

   Pennawd 3: Initially, the designer should acquire a general picture of the network topology. 299s · Speaker 4

   Initially, the designer should acquire a general picture of the network topology. This will help determine the correct information together about network size and its relation to the IP addressing plan. With this general network topology in…

   Pennawd 4: So to reduce the routing overhead in a large network, a multi -level hierarchy might be required. 94s · Speaker 1

   So to reduce the routing overhead in a large network, a multi -level hierarchy might be required. The depth of the hierarchy depends on the network size and the size of the highest level summarization group. So the figure here shows an exam…

5. 13:04

   Pennawd 5: So route summarization groups. 160s · Speaker 5

   So route summarization groups. So what are the impact of poorly designed IP addressing? So a poorly designed IP addressing scheme usually results in IP addresses that are randomly assigned on as needed basis. In this case, the IP addresses …

6. 15:45

   Pennawd 6: Okay, and then if you need 21, so you could get 64 there, of course, with the consideration of the future growth. 65s · Speaker 6

   Okay, and then if you need 21, so you could get 64 there, of course, with the consideration of the future growth. All right, so this is a complete address block by location for San Francisco campus. So using the 172 .16 .0 .0 address block,…

7. 16:50

   Pennawd 7: Okay, so another example is the hierarchical IP addressing plan. 102s · Speaker 5

   Okay, so another example is the hierarchical IP addressing plan. So take note that from the topology that we have, so basically that comprises of the San Francisco campus, the Denver region, and the Houston region. So summarization point ba…

8. 18:32

   Pennawd 8: Now, for the Denver region, 1 ,024 addresses are allocated. 253s · Speaker 4

   Now, for the Denver region, 1 ,024 addresses are allocated. 10 host bits are required. Now, this address block is further divided into smaller subnets supporting buildings, floors, or wiring closets. So that's how you plan distribution of I…

9. 22:45

   Pennawd 9: of course, the end user devices. 98s · Speaker 7

   of course, the end user devices. Just like, for instance, if you are providing a free Wi -Fi access to the end users, so we could put it in a DHCP or dynamic assignment. Okay. Now, number of end user devices. So, well, for static, it could …

10. 24:24

    Pennawd 10: Okay. So let's have an IP assignment or IP address assignment methods in an enterprise network. 301s · Speaker 5

    Okay. So let's have an IP assignment or IP address assignment methods in an enterprise network. So what are the guidelines for assigning IP addresses in the enterprise network? So the typical enterprise network uses both static and dynamic …

11. 29:25

    Pennawd 11: well, static is applicable and so with dynamic. 73s · Speaker 1

    well, static is applicable and so with dynamic. Okay. Next would be, if the network is isolated, okay, how frequently are new hosts added and how frequently do names change? Okay. So these are the recommended practices for name resolution. …

12. 30:39

    Pennawd 12: All right. 203s · Speaker 3

    All right. And then step three, the host establishes a connection to the appropriate IP address, which is www .mywebs .com site. Example of locating DHCP and DNS servers in the network. So DHCP and DNS server locations in the network, as il…

13. 34:03

    Pennawd 13: Okay, so you like what we have here? 95s · Speaker 6

    Okay, so you like what we have here? You've got a pair of colons. All right. So once within an address, that is to represent any successive zeros. So for example, the previous address can be shortened. to the following so initially you are …

14. 35:38

    Pennawd 14: Now, let's talk about IPv6 features. 108s · Speaker 5

    Now, let's talk about IPv6 features. The ability to scale networks for future demands requires a limitless supply of IP addresses and improved mobility. with a more efficient and feature -rich header to meet these demands. Now, IPv6 satisfi…

15. 37:26

    Pennawd 15: All right. 184s · Speaker 3

    All right. So next would be... Header format efficiency. So a simplified header with a fixed header size makes processing more efficient. Next would be improved privacy and security. So IPsec is the IETF standard for IP network security. So…

16. 40:31

    Pennawd 16: Now, the IPv6 unicast addresses is discussed on different types of IPv6 unicast addresses from different sections. 193s · Speaker 4

    Now, the IPv6 unicast addresses is discussed on different types of IPv6 unicast addresses from different sections. Now, this is just to give you an overview about these scope types here. Next would be anycast or one to nearest. So an IPv6 A…

17. 43:44

    Pennawd 17: Okay, now link local addresses are used in the neighbor discovery protocol and the dynamic address assignment process. 303s · Speaker 5

    Okay, now link local addresses are used in the neighbor discovery protocol and the dynamic address assignment process. Now, what is a site local address? So, a site local unicast address are another type of IPv6 unicast addresses. However, …

18. 48:48

    Pennawd 18: which stack to use. 145s · Speaker 1

    which stack to use. So the typical default is IPv6. DNS server for the destination host's address. In this example, it requests the host's IPv6 address. Now, after receiving the response from the DNS server, the application asks the source …

19. 51:13

    Pennawd 19: So let's deal with each of these mechanisms. 274s · Speaker 4

    So let's deal with each of these mechanisms. Let's start with the dual stack mechanism. Now as shown here in the figure, a dual stack node enables both IPv4 and IPv6 stacks. The IP version choice is based on the name lookup and application …

20. 55:48

    Pennawd 20: For IPv4, EIGRP. 75s · Speaker 7

    For IPv4, EIGRP. For IPv6, we also have EIGRP for IPv6. Now OSPF version 2 for IPv4 and OSPF version 3 for IPv6. You also have the integrated ISIS. So this IS -IS here, we're already obsolete, but it makes a huge comeback on the network tha…

21. 57:04

    Pennawd 21: Okay. Now, dynamic address assignment is a recommended practice in the enterprise. 60s · Speaker 6

    Okay. Now, dynamic address assignment is a recommended practice in the enterprise. Specifically, assigning an IP address to the endnotes. So, dynamic name resolution with DNS server is a recommended practice in the enterprise. So, IPv6 was …
