      The Windows Routing Table

      When routers need to forward packets, they interpret the packets’ addresses then use the information in the routing tables to pass the packet on. Data packets contain both source and destination addresses in their packet headers. This is the information that is used when routing decisions need to be made. The destination address is compared

      Understanding Ethernet LAN Segmentation

      LAN Segmentation Overview Network segmentation is the terminology used to describe the process of dividing single Ethernet segments into multiple segments. Network segmentation has the following main advantages: Network performance of the LAN is improved. Network congestion issues can be resolved. Available bandwidth is maximized. A few technologies which you can use to perform network

      The VPN Gateway

      Virtual Private Networks (VPNs) enable users to connect to a remote private network through the Internet. Virtual private networks therefore span the Internet because the user connects over the Internet to the remote VPN server. With a VPN, data is first encrypted and encapsulated before it is sent to the remote VPN server. When the

      NetBIOS Node Types

      A NetBIOS node type is a method that a computer uses to resolve a NetBIOS name into an IP address. A NetBIOS node type allows an administrator to configure the order and method that a client uses when resolving NetBIOS names to IP addresses. Understanding how the various node types function will help users to

      NetBEUI

      NetBEUI (NetBIOS Extended User Interface) is a program used for communication between applications installed on separate computers within the same LAN (Local Area Network). It is an upgraded version of NetBIOS and provides much more flexibility and functionality by rearranging the information in a data transmission. Like NetBIOS, NetBEUI is not a networking protocol and

      How to Remove IPv6 in Windows

      IPv6 stands for Internet Protocol version 6. IPv6 is the latest version of the network-layer protocol for packet-switched networks. The version that is generally used is IPv4. One of the reasons for the upgrade to IPv6 is that it allows greater space and flexibility in assigning IP addresses. For instance, IPv4 is based on a
