Research Paper NT1430 Essay

When it comes to IPv6 there are a lot of topics that can be discussed. It go away change the Internet forever as we know it. IPv4 is the fourthly version of protocol using a 32 chipping hail space whereas IPv6 will be using 128 bits of hexadecimal addressing to allow for drastically more addresses. Currently IPv4 allows roughly 4,294,967,296 viable addresses and with the current allocation practices it limits the phone number of public address to a few hundred million. In contrast, the 128 bit address space that IPv6 uses can provide roughly 3.4 x 1038 possible addresses.The sheer size of the IPv6 address allows for the subdividing of the address into a hierarchical routing complex body part that in turn can reflect the current topology of the Internet. This will provide great flexibility for the addressing and routing in the future where the IPv4 obviously lacks in comparison. It would hard to imagine a world where we do have any longer Internet addresses to go around. This s hould hopefully solve that problem, at least for a while to come.When configuring DHCP on Linux to use IPv6 one must be certainly that they have everything in order. The two most used means of motorcar shape IPS are on the router advertisement and dhcpv6. When you are using the RA a server daemon needs to advertise a intercommunicate prefix which is typically a /64, gateway and sometimes a DNS server. then the Client machines can auto configure their IPv6 addresses when they have initialized a bootup establish on their current MAC address using EUI64.When addressing the same posture with dhcpv6, dynamic or static addresses can always be assign to the current client machines. Unfortunately the gateways cannot be assigned due to the tendency of the dhcpv6 protocol. If you must use dhcpv6 you have to use RA. You can configure RA to advertise only the gateway leaving the IP and DNS server kind all up to the dhcpv6, or only the DNS servers. In order to gush dhcpd in IPv6 mode y ou need to add a -6 argument.The arguments should define the configuration file and lease file. here(predicate) is an example of a startup postulate /usr/sbin/dhcp -6 cd/etc/dhcpd6.conf lf/var/state/dhcpd6.leases eth1. The -6 enables the IPv6 mode and the cf defines the IPv6 configuration file. Heres an example of the dhcpd6.conf dhcpd6.conf authoritative option dhcp6.name-servers cc1db811200 option dhcp6.domain-search internal.1anIn conclusion, I hope that after this you understand wherefore IPv6 is such a game changer and why it is so cardinal for our world going forward. Without it our planet would cease to exist and everything would stop. Obviously IPv4 is lock around and will be for a few more years, precisely the days of thinking that IPv4 would last forever or definitely everywhere and its time for something new will hopefully last a little longer.Referenceshttp//technet.microsoft.com/en-us/library/cc780310(v=WS.10).aspx //www.cisco.com/web/about/security/security _services/ciag/documents/v6-v4-threats.pdf http//linux.ardynet.com/ipv6setup.php
