192.168.0.1 is a private IP address that is commonly used by Netgear and D-Link routers. The Netgear and D-Link brands are competitors to the Linksys division of Cisco, Incorporated and make a large number of the Internet routers used world-wide. The network address is not granted to the Netgear and D-Link companies exclusively; however, as …
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 …
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 …
A computer network can be segmented physically and logically. A collision domain is one of the logical network segments in which the data packets can collide with each other. One of the most common protocols used when referring to a collision domain is the Ethernet protocol. Collision domains are often referred to as ‘Ethernet segments.’ …
Subnetting is the process of breaking down an IP network into smaller sub-networks called “subnets.” Each subnet is a non-physical description (or ID) for a physical sub-network (usually a switched network of host containing a single router in a multi-router network). In many cases, subnets are created to serve as physical or geographical separations similar …
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 …
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 …
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 …
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 …
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 …
