  1. Understanding IPv6 Link-local Addresses Zone IDs

    As we have noted in a previous post all IPv6 Link-local Addresses (LLA) share the same network identifier (fe80::) hence, you can cannot determine which interface an LLA is bound to, if the computer has multiple network adapters connected to different network segments. In fact, it distinguishes the networks by using a numeric zone ID, following a percent sign after... Read More

  2. IPv6 Link-Local Addresses

    Pv6 Link-Local Addresses (LLAs) are similar to APIPA (Automatic Private IP Addressing) addresses in Windows IPv4 based systems. APIPA addresses are self-configured, non-routable addresses in the range of 169.254.0.0/16. But unlike APIPA addresses, LLA addresses remain assigned to an interface as a secondary address even after a routable address is obtained for that interface. An LLA address always begins with...

  3. IPv6 Global Address Structure

    IPv6 global addresses are equivalent to Public IP addresses in IPv4 and are globally reachable on the IPv6 portion of the Internet. The global IPv6 address structure is divided into three parts, the Public and Private routing part, and the host identification within a LAN. These parts add up to 128 bits which are structured as follows: The first 48... Read More

  5. IPv6 Technologies

    Organizations are looking into the details of IPv6 and see if they are ready to shift from IPv4. For instance, IPv6 has a new header format, and hence, IPv4 routers that have not been designed to support IPv6 cannot parse the fields in the IPv6 header. On the other hand, Layer 2 protocols are not affected where internal switches and... Read More

To install the Print Services server role with the Print Server and Internet Printing role services follow... Read More

  8. Windows Server 2008 Printers commands

    Windows Server 2008 and Windows 7 include tools that help you manage printers from the command prompt using Visual Basic scripts. You can find these scripts in the Windows\System32\Printing_Admin_Scripts\en-US\ folder. Since these tools are Visual Basic scripts you need to run the cscript command and pass the full path to the script file as the first parameter. Additional parameters can... Read More
