      QoS (Quality of Service)

      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 –

    • IP (Internet Protocol)

      IP (Internet Protocol)

      The primary network communications protocol used on networks today is the IP (Internet Protocol). IP relays or transfers network packets, also known as datagrams, to destinations on local networks or across the public Internet. It defines the structures which encapsulate information as well as the legal addressing methods used to identify the source and destination

    • IP Address

      IP Address

      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.

      How to Use Ping to Test a Network

      The following steps elaborate on how to use the Ping utility to perform progressively more distant tests on network connectivity. Ping the Loopback Address – Type Ping 127.0.0.1 Successfully pinging the loopback address verifies that TCP/IP is both installed and configured correctly on the local client. If the loopback test fails, it means IP stack

    • How to Set a Static IP

      How to Set a Static IP

      An IP (Internet Protocol) address is a unique identifier for any device that connects to the Internet. All computers, modems, routers, mobile devices, and even accessory items such as printers, scanners, and fax machines have an IP address. IP addresses are extremely common in the web design industry because every website must be associated with

    • Broadcast Address

      Broadcast Address

      A broadcast address is an IP address that targets all systems on a specific subnet instead of single hosts. The broadcast address of any IP address can be calculated by taking the bit compliment of the subnet mask, sometimes referred to as the reverse mask, and then applying it with a bitwise OR calculation to

    • DHCP Reservation

      DHCP Reservation

      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

    • What is a Zeroconf?

      What is a Zeroconf?

      Zeroconf (zero configuration networking) refers to several protocols and techniques that are used together to create an IP (Internet Protocol) network with no special configuration servers or manual operator intervention. These networks allow novices to connect computers, network devices, scanners, and printers to create a functioning network without requiring manual configuration. Zeroconf does not require

    • DHCP Scope

      DHCP Scope

      A DHCP scope is a valid range of IP addresses that are available for assignment or lease to client computers on a particular subnet. In a DHCP server, a scope is configured to determine the address pool of IPs that the server can provide to DHCP clients. Scopes determine which IP addresses are provided to

    • 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
