      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

    • traceroute

      traceroute

      traceroute is a command which is used to trace the route of a packet through a TCP/IP network. traceroute is a Unix command. Under Microsoft Windows, the traceroute command has been renamed `tracert`. Unix `traceroute` and Microsoft Windows `tracert` are designed to accomplish the same task, but differ in the way they display output, in

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

      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

    • MPLS (Multi Protocol Label Switching)

      MPLS (Multi Protocol Label Switching)

      MPLS stands for Multi Protocol Label Switching. The MPLS is often referred to as the layer in between the Data Link and Network layers because of where it operates. The MPLS serves as a method to forward packets of data easily by using labels. What are the Data Link and Network layers? In the seven-layer

    • 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

    • Routing Tables

      Routing Tables

      A routing table is a grouping of information stored on a networked computer or network router that includes a list of routes to various network destinations. The data is normally stored in a database table and in more advanced configurations includes performance metrics associated with the routes stored in the table. Additional information stored in

    • ICMP (Internet Control Message Protocol)

      ICMP (Internet Control Message Protocol)

      ICMP is the Internet Control Message Protocol. ICMP is a complementary protocol to IP (Internet Protocol). Like IP, ICMP resides on the Network Layer of the OSI Model. ICMP is designed for sending control and test messages across IP networks. Unlike the Transport Layer protocols TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) which

    • Subnet Masks

      Subnet Masks

      A subnet mask allows users to identify which part of an IP address is reserved for the network and which part is available for host use. By looking at the IP address alone, especially now with classless inter-domain routing, users cannot tell which part of the address is which. Adding the subnet mask or netmask

    • NAT (Network Address Translation)

      NAT (Network Address Translation)

      NAT (Network Address Translation) is a technique for preserving scarce Internet IP addresses. Why NAT? The current Internet uses IP addresses in the form xxx.xxx.xxx.xxx. A sample IP address might be 202.187.4.212. Because of the way these IP addresses are allocated, there started to be a shortage of available IP addresses. The current IP (Internet

      BOOTP

      BOOTP is the Bootstrap Protocol. The BOOTP protocol is utilized by diskless workstations to gather configuration information from a network server. The information provided by the BOOTP protocol is: The IP address which should be utilized by the diskless workstation The IP address of a server which will provide an Operating System image for the
