Advantages And Disadvantages Of Ip V6

Ans: Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers configured for a given network.

Primary function of IP protocol = identify individual hosts and groups of hosts using the address

The Dynamic Host Control Protocol automatically assigns IP addresses to hosts on a network as they request them. DHCP packets also include information like DNS server addresses, domain names, and default gateways.

IPv6 uses a128-bit address size compared with the 32-bit system used in IPv4 and will

pieces. The data packet is sent to a gateway computer which either recognizes the address

Each of the values are used to determine the difference between a data and context packets, as well as the packet count, the packet size, identifying bits that determine the presence of header features. Figure 4 is a template for the data packet.

Protocol capture tools and protocol analyzers are important tools for an information systems security professional. These utilities can be used to troubleshoot issues on the network. They can verify adherence to corporate policies, such as whether or not clear text privacy data is being sent on the network. They can be used to test security countermeasures and firewall deployments and are needed to perform audits, security assessments, network baseline definitions, and identification of rogue IP devices.

IPv6 uses NDP (Neighbor Discovery Protocol) to find the MAC address. NDP manages interaction between nodes via message exchanges. These messages provide the data necessary for the processes of host auto configuration and packet transmission on a local link. Host auto configuration involves separate tasks of Parameter discovery, address auto configuration and duplicate address detection. Packet discovery is facilitated through router discovery process. It obtains the necessary parameters required for host configuration. Duplicate address detection is used to detect the presence of duplicate addresses on the same link. Packet transmission process requires data which can be obtained by router discovery, prefix discovery, address resolution, neighbor

The Internet Protocol (IP) has some vulnerability that can be exploited to transfer information along the network by being anonymous. Some attempts have been made using IPv4 but now since IPv6 is the new mode of network the challenge is to design it to fit the new trend.

To outface this problem Network Address Translation (NAT) method is used. This enables devices with private addresses to be connected to a public network address (e.g. Internet). This private address is converted to legal IP address, through NAT routers before traveling 11 “outside”. (See figure 4). Every device that is connected to the network has a unique IP address but this doesn’t mean that is permanent. Because devices connected to the network,

IPv6 is not a solution for security, however, in light of the fact that few security issues

Compare the packet’s destination IP address to the routing table, and find the route that matches the destination address. This route identifies the outgoing interfaces of the router, and possibly the next-hop router.

The reason why the address is longer in v6 is because it can support over 340 undecillion IP addresses. Mainly because the IPv6 has potential to have problems just like the IPv4 address problems. Also, the IPv6 has been broken down into geographical locations, meaning that the address can be tracked to a specific location in the world. The downfall in this part, in my opinion, in a hacker’s point of view, is that you can breakdown a specific location where you would want to attack, if you know the geographic location of the hexadecimal in the address. What I mean is that you can know the country code in the IPv6 address and focus your attack in that specific location. Having a random order of the v6 address would make it more reliable and more secure but also would allow disorder, not knowing where specific address might be located.

More sooner than later the internet will transition to IPv6 rather than the current IPv4 standard; this is partially due to very few IPv4 network address available (Haugh, 2012). Many large companies are already using the IPv6 internet protocol and using it now will prevent having to reengineer the network at a later timeframe (Wong, 2011). Even though the local ISP may require IPv4, in the short term, that can be overcome by using IPv4 and IPv6 dual stack tunneling (Beverly, 2015). This allows external IPv4 address conversion to IPv6 with the configuration of the internet facing network address translating (NAT) router.

Figure 1.8 code trees with the four layers are taken into account. The highest capacity of the code tree is 8R. In the code tree, two codes with SF is 4 and 8 are engaged. As a result, the capacity employed for the OVSF code tree is 3R. The remaining capacity of the code tree is 8R-3R=5R. When a new call with data rate 4R enters, code from the third layer is essential. The code tree is not capable of offering code for the new call, since both the codes equivalent to 4R capacity are obstructed. Accordingly, this is a condition where a new call capacity to manage it. This is known as code (call) blocking and can be circumvented with the help of efficient assignment and reassignment
