![]() Practical Activity 1.Įxecute the following commands and document their output. In our example the web socket would be 192.168.0.50:80. The combination of an IP address and a port number is called a socket. The first 1024 ports are reserved for use by certain privileged services: The FTP server receives the request, generates the response,and sends it to the host’s IP address and port. The host use the locally unused port of 1200 for communication. Because FTP servers use, by default, the well-known port 21, the host generates the request and sends it to the FTP server’s IP address and port. In the picture above you can see that a host with an IP address of 192.168.0.50 wants to communicate with the FTP server. A client can use any locally unused port number for communication. A client can request the service by pointing the request to the application’s IP address and port. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) specify the source and destination port numbers in their packet headers and that information, along with the source and destination IP addresses and the transport protocol (TCP or UDP), enables applications running on hosts on a TCP/IP network to communicate.Īpplications that provide a service such File Transfer Protocol (FTP) and Hypertext Transfer Protocol (HTTP) servers open a port on the local computer and listen for connection requests. The Network ID and the bits used for the Hosts ID.įor each network class A, B or C, there is a defaultĪ port is a 16-bit number used to identify specific applications and services. The mask defines the bits that are used for “masks” the associated IP address assigned with it. Internal network, particularly when the machines getting IP addresses have noĬhance of ever servicing people’s requests on the Internet.Ī subnet mask is another 4-octet, 32-bit address that Where possible, always use private addressing in your Each number is the decimal (base-10) representation for an eight-digit binary (base-2) number, also called an octet. An IPv4 address is expressed by four numbers separated by dots. IPv4 uses 32 binary bits to create a single unique address on the network. MAC addresses are shown as Hexadecimal numbers from 0 -E. If you still cannot access websites with WAN IP address, go to Interface Setup > LAN and change the DNS server to Use User Discovered DNS Server Only and set to 8.8.8.8 and 8.8.4.4, then try again.First three bytes are the Vendor ID, The second three bytes are the interface ID If WAN IP address is 0.0.0.0, please contact your Internet Service Provider to verify whether your configuration info provided is correct.Ģ. Go to the Status page to check the WAN IP, and make sure the Status is Up.ġ.

Use admin (all lowercase) for both username and password, and then click Login.ģ. Launch a web browser and enter or 192.168.1.1 in the address bar. The default SSID (Network Name) is on the modem router’s label.ģ. Wireless: Connect your computer or smart device to the modem router wirelessly. Wired: Connect the computer to a LAN port on your modem router with an Ethernet cable. Connect your computer to the modem router (Wired or Wireless). Note: If you don’t need the phone service, just directly connect the modem router to the phone jack with the provided phone cable.Ģ. Connect the hardware according to the diagram below, and wait about 1 to 2 minutes, then verify that the Power, ADSL and Wi-Fi LEDs are on.
