|Title||Operating System Response to Router Advertisement Packet in IPv6|
|Title in Arabic||استجابة انظمة التشغيل للحزم الاعلانية للموجهات في برتوكول IPV6|
With growth of internet IPv4 address will run out soon. So the need of new IP protocol is indispensable. IPv6 with 128-bit address space is developed and maintain the support of IPv4 protocols with some upgrades such as BGP, OSPF and ICMP. ICMP protocol used for error reporting, neighbor discovering and other functions for diagnosis, ICMP version 6 has new types of packets to perform function similar to address resolution protocol ARP called Neighbor Discovery Protocol NDP.NDP is responsible for address auto configuration of nodes and neighbor discovery. It define new packets for the purposes of router solicitation, router advertisement and others discovery functions. These RA’s messages are responsible for auto configuration IP address in version 6 protocol and other information such as DNS information and Gateway. Using three flags (A, M and O) RA message can advertise the OS with proper configuration. Many question will answered at the end of research: What is the configuration for all combinations are set automatically? What will happen when all flags are set? How has the priority when two flags or more are set? What should happen if IP address and DNS information is obtained from two sources on the same link? In this research the ambiguity of router advertisement behavior is removed. These RA messages will be set with different values. Then, discover the auto configuration IP address and DNS options for operating system response. These configurations are the aim to this research. Many public OS’s compared in the research form different vendor such as Linux, Microsoft and Mac. The main simulator is GNS3 for network topology. Hosts attached to GNS3 using VMware workstations. Wire shark is used as network analyzer packets flow.
