Question
Imagine that your department or lab has decided to upgrade from IP version 4 (IPv4) to IP version 6 (IPv6).
1. Inventory the current devices on the network. Gather rough counts, manufacturers, and models of the NICs switches, routers, and other network devices that participate on the network.
2. Research the various network devices and determine if they are already IPv6 compatible.
3. For those devices that only support IPv4, determine how much it would cost to replace the device with one that provides the same functionality but supports IPv6.
4. Total the costs and organize your findings into an executive-level presentation to convince management of the need (or lack thereof) to upgrade. Base your recommendation on whether the benefits of IPv6 outweigh the costs.
Explanation / Answer
Complete trasition fromIPV4 to IPV6 not possible beacuse IPV6 is not backward compatible.To overcome this problem we have a few technologies that can used to ensure slow and smooth transition from IPV4 to IPV6.
1.By using DualStackRouter.
2.Tunneling
3.NAT - Protocol Traslation
1.Devices used in this server are Dual stack implies providing complete impletation of both versions of the Internet Protocol (IPV6 and IPV4)
2.tunneling provides a means to carry IPV4 packets over unmodified IPV$ routing Infrsstructures.
3.Tunnel MTU is used to foxed the bytes of information by default.
4.DNS(Domain Name Service)is used both IPV6 and IPV4 to map between hostnames and IP addresses.
2.This IPV6 server mainly used in CISCO Software.because it supports an unlimited number of global addresses.
3.IPV4 devices is not designed to a backward compatibility.the IPV6 is redesigned entirely.It having the Extra features like Large Address Space,Simplified Header,End to end connectivity,Auto Configuration,Fast forwarding or Routing,IPsec,Mobility etc..
4.Ipv6 doesnot fully support the Windows,It is possible to incude an IP address within a Universal Naming.The IPV4 does not support the IPV6.The IPV6 does not support IPV4.
Benifits of IPV6:
1.The address size is different withIPV4 having 32 bit number,while IPV6 having 128-bit number.
2.IPV4 octet formate is 4octets and IPV6 is 16 octets.
3.IPV6 supporting the Backward compatibility.
4.In IPV6 no translation is neccesary because every device can have its own address reason is using Network Address Translation.
5.Using Dual IP Layer it can provide complete support for both INternet protocols IPV4 and IPV6 in hosts and routers.
