格里菲斯大学Assignment代写: 向IPv6过渡

IP地址是一个数字地址,它给任何机器想成为一个成员或连接到一个计算机网络,它用来识别任何连接到计算机网络的节点。目前的IP地址,一直以来1981的当前版本是IPv4。此外,不断增加的需求,使用或访问互联网资源和全球网络的数量的急剧增长将导致IPv4地址空间耗尽由于它的局限性。此外,IPv4的枯竭引发设计IPv4和置换的理念将IPv6。向IPv6的过渡将是我要讨论在这篇文章中的问题。这篇文章将涵盖几个关于这个问题如IPv4和IPv6之间的差异方面,评价了IPv4地址耗尽和过渡方法的简要描述问题。此外,IPv6的现状将被覆盖,网络管理员可能需要改变,为了向IPv6过渡的服务如地址分配,地址自动配置,DNS服务器,Internet的WWW服务器、电子邮件、防火墙和本地服务,如打印机。

首先,它有助于从IPv4和IPv6之间的差异进行转化的理念和明确的对我们的好处。IPv4不同,如地址空间,几个方面的IPv6地址配置,安全性、多播、广播、路由和移动性。IPv4和IPv6之间的主要区别是,IPv6比IPv4大得多,这是IPv6的重要特征。IPv6是128位(16字节)长度在IPv4的32位(4字节)长度和IPv6子网是固定的(64位)。此外,IPv4在十进制格式如是192.168.0.16虽然IPv6是十六进制格式化表示:X X X X X::::::X X X,X代表每16位或四进制数字例如2001::::370:3473 8a2e db8:85a3。另一个区别是,在IPv6地址配置自动在IPv4网络管理员需要手动或通过使用DHCP。此外,在IPv4的安全或使用IPSec是可选的而在IPv6是强制性的,另一个词是IPv6结构部分。多播是IPv6与IPv4是可选的设置并没有播出,我们可以为IPv6组播的应用在一个特定的网络广播。此外,IPv6与IPv4,IPv6支持QoS的分组流识别在IPv6报头的任何碎片或校验和。

IP address is a numerical address which is given to any machine wants to be a member or connected to a computer network and it used to identify any nodes connected to a computer network. Nowadays, the current version of the IP address that has been used since 1981 is IPv4. In addition, the increasing demand of using or access the internet resources and the dramatic growth of the number of the networks around the world will lead to exhaustion of IPv4 address space because of the limitation of it. Moreover, the exhaustion of IPv4 triggered the idea of redesign IPv4 and the replacement will be IPv6. The transition to IPv6 will be the issue that I am going to discuss in this essay. This essay will cover several aspects about this issue such as the differences between IPv4 and IPv6, evaluate the problem of IPv4 address exhaustion and a brief description about the transition methods. Furthermore, the current state of IPv6 will be covered and the services that the network administrator might need to be changed in order to transition to IPv6 such as address allocation, automatic address allocation, DNS server, internet WWW server, email, firewalls and local services like printers.

First of all, it is really helpful to start with the differences between IPv4 and IPv6 to make the idea and the benefits of the transition clear for us. IPv4 differ from IPv6 in several aspects such as address space, address configuration, security, multicast, broadcast, routing and mobility. The major difference between IPv4 and IPv6 is that IPv6 is much larger than IPv4 and this is important feature of IPv6. IPv6 is 128 bits (16 byte) length while IPv4 32 bits (4 byte) length and the subnet in IPv6 is fixed (64 bits). Furthermore IPv4 expressed in a decimal format e.g. 192.168.0.16 while IPv6 is formatted in hexadecimal x:x:x:x:x:x:x:x where each x symbolizes 16 bits or four hexadecimal digits e.g. 2001:db8:85a3::8a2e:370:3473. Another difference is that the address configuration in IPv6 is automatically while in IPv4 the network administrator needs to do it manually or by using DHCP. In Addition, the security or using IPSec in IPv4 is optional whereas it is compulsory in Ipv6, on another word it is part of IPv6 structure. Multicast is provided in IPv6 unlike IPv4 which is optional and there is no broadcast in IPv6 where we can use multicast in order to apply broadcast on a particular network. Moreover, IPv6 unlike IPv4 where IPv6 supports QoS by identifying packet flow and there is no fragmentation or checksum in the packet’s header in IPv6.
