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 small business routers. Beyond initial router configuration, 192.168.1.1 is commonly used to troubleshoot network connectivity issues with Linksys networking products. These issues can range from a loss of connectivity to the end-user just forgetting the Read More

QoS stands for Quality of Service. QoS is a generic name for a set of algorithms which attempt to provide different levels of quality to different types of network traffic. Queuing One method of implementing QoS is to utilize some sort of advanced queuing algorithm. Simple networks process traffic with a FIFO (First In – First Out) queue. Packets which are received first are processed first. QoS comes into play when the network admin wants to treat some packets differently than others. For example: e-mail packets can be delayed for Read More

VRRP stands for Virtual Router Redundancy Protocol. The VRRP is a commonly used method to avoid network outages during important data transfers. Data transfer can be highly susceptible to failure when sent by a single router network. To combat this problem, VRRP creates a virtual connection between routers within the same network and ties them together. If the initial router used to send the data fails for any reason, another router automatically takes over the transfer. Is the VRRP a physical router? No. The VRRP is, as the name indicates, Read More

A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client. Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment. Reservations are used for DHCP enabled devices like print and file servers or other application servers that always have the fixed IP address on the network. A reservation consists of the following information: Element Description Reservation name Name that Read More

An IP (Internet Protocol) address is a unique address that different computers on a computer network use to identify and communicate with one another. An IP address is used as an identifier to find electronic devices connected to one another on a network. Therefore, each device in the network must have its own unique address. An IP address is like a mailing address that is used to deliver data (files) to a computer. Some IP addresses are meant to be unique within the scope of the Internet, whereas others are Read More

192.168.2.1 is a private IP address commonly used by the SMC and Belkin router manufacturers for device setup and troubleshooting. SMC and Belkin specialize in manufacturing home networking equipment that competes with Netgear, D-Link, and Linksys brands in the marketplace. The Internet Assigned Numbers Authority (IANA) does not grant exclusive use of the IP address to these companies; however, as other network equipment manufacturers are free to use the IP address if required or desired. If another router or networking device is installed on a local network which uses 192.168.2.1, Read More

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, and cumbersome experience. When you manually assign IP addresses, you increase the risk of duplicating IP address assignments, configuring the incorrectsubnet masks, and incorrectly configuring other TCP/IP configuration parameters. This is where the Dynamic Host Read More

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 of the competing open source routing software packages. Quagga Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPv3 and BGPv4 for Unix platforms, particularly FreeBSD, Linux, Solaris and Read More

The IP address is a logical address assigned to a network card in order to establish communication over the network and identify the computer over it. Network administrators usually assign IP addresses based on certain rules and regulations. Reasons to Change an IP Address Even if someone is part of a small network routed through a single IP address, the people outside that network can only see the IP address of the gateway being used. If someone is directly connected to the Internet cloud, it is basically the same thing. Read More

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 example shows the creation of a null route for an entire Class C network: # route add 193.252.19.0 0.0.0.0 add net 193.252.19.0: gateway 0.0.0.0 We can see the route which this command created using the Read More
