ipv6 RRS feed

  • Question

  • Among the 300 PCs and servers with updated OS with  a company, is machines distributed as follows: 70 Windows XP Professional 90 Windows Vista Enterprise 120 Windows 7 Enterprise 15 Windows 2008 Server Enterprise 2 Windows 2008 Server Standard 3 Windows 2003 Server Standard All OS are regularly updated from a central WSUS which sends updates to 3 second WSUS servers. 

    traffic is generated by TCP/IPv6. This traffic is generated by LLMNR, Neighbor Discovery, the generation of Link Local Addresses, and the like. The network has a complete infrastructure consisting of DNS, DHCP and Active Directory in the mode that is compatible for the 2003 servers,

    should the trafic be limited or raffic should be limited or removed entirely or  should continue as the network still soon to specify a plan for full implementation IPv6 over a two-year period?

  • Hi!

    To be straight, your question is both hard to read and to understand!

    Microsoft strongly recomments that IPv6 should stay enabled on all systems running Windows Server 2008, Windows Vista, and higher!

    So, it is normal that you'll see some IPv6 related traffic in your network! According to RFCs, IPv6 has priority over (the deprecated) IPv4! All systems try IPv6 at first!

    My advice: A) Leave IPv6 enabled on ALL systems, B) enable your DNS servers to accept IPv6 name resolutions as well, C) make the machines running the newest versions of Windows your AD Controllers, DHCP servers and DNS servers, and finally D) think of both decommisioning your WINS servers and introducing DHCPv6.

    Hope that helps... :-)
