      What is PCAP?

      PCAP (Packet Capture) is a protocol for wireless Internet communication that allows a computer or device to receive incoming radio signals from another device and convert those signals into usable information. It allows a wireless device to convert information into radio signals in order to transfer them to another device. PCAP runs in the background

      How Unix and Windows traceroutes differ

      The Unix/Linux `traceroute` command and the Microsoft Windows `tracert` commands both accomplish the task of tracing network paths, but they do it in slightly different ways. Both of these tools for tracing network routes send out a packet wth TTL (Time To Live) set to 1 and report it’s destnation. Then, they send out a

    • 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

    • 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

    • 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

    • 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

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

      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

    • 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

    • 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

    • 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
