      What is an L2TP?

      L2TP (Layer Two Tunneling Protocol) defines an extension to PPTP (Point-to-Point Tunneling Protocol) that an ISP (Internet Service Provider) uses to allow a VPN (Virtual Private Network) to operate. L2TP combines L2F from Cisco Systems’ optimum features and PPTP from Microsoft into a single protocol. L2TP’s two primary components are the LNS (L2TP Network Server)

      192.168

      The Internet Assigned Numbers Authority (IANA) has allocated three IP address ranges that are to be exclusively used for private Internet networks: 10.0.0.0 – 10.255.255.255 (10/8 prefix) 172.16.0.0 – 172.31.255.255 (172.16/12 prefix) 192.168.0.0 – 192.168.255.255 (192.168/16 prefix) The first block “10.0.0.0 – 10.255.255.255” is referred to as the 24-bit block, the second “172.16.0.0 – 172.31.255.255”

      192.168.1.1 – What Are its Uses and Why is it Important?

      The 192.168.1.1 IP address is a default commonly used by Linksys routers. Linksys is now a division of Cisco, Incorporated and makes a large number of the broadband routers used throughout the world. The address is not exclusive to Linksys, but most other major router manufacturers use different default addresses for configuration of home or

    • Null Route

      Null Route

      A null route is a route that goes to nowhere. The reason for creating a null route is to prevent your system from sending any data to a remote system. Creating a null route Null routes are usually created using the `route` command. This works under both Windows and Unix, although the syntax differs. The

    • Routing Protocols

      Routing Protocols

      A routing protocol is the implementation of a routing algorithm in software or hardware. A routing protocol uses metrics to determine which path to utilize to transmit a packet across an internetwork. The metrics that routing protocols use include: Number of network layer devices along the path (hop count) Bandwidth Delay Load MTU Cost Routing

    • Routing Software

      Routing Software

      Most networks currently run on hardware-based routers from vendors like Cisco, Foundry, and Juniper. Computing power has advanced to the point where this is not necessary. General purpose computing platforms can replace these expensive dedicated hardware routers. These software routing platforms usually run on some version of free or inexpensive Unix. These are a few

    • Static Route

      Static Route

      A static route is one that a network administrator creates manually. The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols. Static routes have advantages and disadvantages when compared to dynamic routes. Advantages of Static Routes: Easy to configure No routing protocol overhead Disadvantages of Static Routes: Network

      How to Find a LinkSys Router IP

      Linksys is the home networking division of Cisco, Incorporated and has significant penetration in the U.S. home networking market. A common question that arises for consumers who are new to home or small business networking is determining how to find a Linksys router IP address on a new or legacy network. When shipped from the

      DHCP (Dynamic Host Configuration Protocol)

      An IP address can be defined as a unique numeric identifier (address) that is assigned to each computer operating in a TCP/IP based network. Manually configuring computers with IP addresses and other TCP/IP configuration parameters is not an intricate task. However, manually configuring thousands of workstations with unique IP addresses would be a time consuming,

    • Broadcast Domain

      Broadcast Domain

      A broadcast domain is a logical part of a network (a network segment) in which any network equipment can transmit data directly to other equipment or device without going through a routing device (assuming the devices share the same subnet and use the same gateway; also, they must be in the same VLAN).
