What Is The IP Address Of A Web Server?

A network interface card is already present in the computers. The purpose of the network card is to enable the computers to connect together using a protocol in order to transfer packets of data. In order to connect the computers, a form of connection is required that links the computers. In this case the form of connection used will be ethernet (Science - Opposing Views, 2014).

Protocol capture tools and protocol analyzers are important tools for an information systems security professional. These utilities can be used to troubleshoot issues on the network. They can verify adherence to corporate policies, such as whether or not clear text privacy data is being sent on the network. They can be used to test security countermeasures and firewall deployments and are needed to perform audits, security assessments, network baseline definitions, and identification of rogue IP devices.

First, let’s talk about Wireshark, it is the most common network packet analyzer used worldwide, perhaps one of the best open source (free) packet analyzers today. It lets you capture and interactively browse the traffic running on a computer network, helping you analyze and manage the traffic in your network. Like a measuring device used to examine what is going on in your network cable, like a voltmeter used by an electrician to examine what is going on inside an electric cable. Therefore, gives you the tools to do in depth network analysis, it will try to capture network packets and display them as detailed as possible for analysis. Furthermore, used for troubleshooting network problems, examine security problems, debug protocol

When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.

Every Computer that connects to a network must have a Network Interface Card (NIC). Most new Computers have them built into the motherboard. It has one or sometimes more RJ45 socket(s) that connect to a modem. The older and deprecated version used to have RJ11 sockets to connect to the network. Due to it being extremely vulnerable to phreaking and war-dialing, it has now been replaced with

Also cable lines running to fiber optic lines, through routers. And lastly it could be radio waves that computers can broadcast and receive or a combination of the above mentioned which are connected to enable communication via a modem, network card, radio transmitter, or router etc… sending your credentials in packets from your console through cabling to local access networks, regional networks, core/long-haul networks and ocean networks.

Wireshark is an open-source program which enables users to actively capture and interact with the network traffic which is being funnelled through the computer. Commonly, pieces of software which do this are referred to as ‘packet sniffers’ - As the program is recording the packets which pass through the network.

Sockets is the form of communication (UDP and TCP) use the socket abstraction, which provides an endpoint for communication between processes to processes. Interprocess communication consists of transmitting a message between a socket in one process and a socket in another process. As the IP packets underlying UDP and TCP are sent to Internet addresses.

You can view your IP address for a NIC (or network adapter) by double-clicking one of the available connections in the Network Connections window (accessible from the Control Panel) and selecting the Support tab, just as you did when you were finding your MAC address. This information is also given in the Details window where you found the MAC address. What is the IP address of your NIC or network adapter? What is the IP address listed for your default gateway?

After installation, go to Device Manager and expand “Ports (COM & LPT)”. You should see this if your installation was successful:

In my first screenshot, I have captured 4888 packets from my Local Area Connection. Within the first screenshot it shows the capture filters which includes TCP, IPX, UDP, etc. Furthermore, it’s just showing how to capture packets within a network. Wireshark is a sniffer that helps the user search within packets that allows it to be monitored to be analyzed with data. The purpose of this Hands-on Activity 4A, was to have the student experience and learn how to download and use a software (Wireshark) to increase their knowledge of advantages and disadvantages are within a sniffer. The steps I took were to browse the selection of the options provided on the program. I read some of the instructions in the textbook, Business Data Communications

Also, UDP is connectionless which means that there is no need for creating a connection first before sending out data and have more control over when data is sent out. Because data corruption is a common occurrence on the internet, UDP has a primitive form of error detection but it is not that reliable because it doesn't recover the error it just will be discarded. Even if the network is busy, UDP will try to cram packets in the network and this is a bad strategy because it will cause more collisions. Here where TCP comes, for having certain features that make the connection more reliable. However, it also has a bigger communication over than UDP. TCP's connection is based on negotiating first before doing anything, this known as the three-way handshake. If any error is detected, TCP offers retransmission when a receiver doesn't get a delivery a package. So, it will send it again guaranteeing your data to reach its destination in time and without duplication. Since all the work is done by the operating system, It automatically breaks up data into packets for you. So you just need to sit back and watch the show. Even the debugging is taken care of by your OS and if there are bugs in your OS, then you will face many problems like problems in surfing and downloading contents from the net. I do prefer the TCP service because it does all the work for you

that it's a local area network II / web Protocol Version four / Transmission management Protocol / Secure Sockets Layer frame. Additionally notice that the local area network II, web Protocol Version four, and Transmission management Protocol values area unit in line with the transmission control protocol affiliation analyzed in Activity three.

basis, which list information about the sending router. Included in the packets are a series of

There are two types of Internet Protocol (IP) traffic, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Some of the features that UDP possesses that are not provided by TCP/IP. First, UDP is a connectionless protocol (No handshake), which means packets sent from one node to another without making sure whether any packet may be lost during the transfer. TCP, on the other hand, makes sure to establish a connection in order to send the packets from one node to another without losing any packets. It is also known as handshake process, where nodes synchronize (SYN),
