In TCP/IP communications, the IP Address is analogous to a telephone number and the port number would be analogous to a particular extension once the call has been answered. The “Client” in a TCP/IP connection is the computer or device that “dials the phone” and the “Server” is the computer that is “listening” for calls to come in.

A socket programming interface provides the routines required for interprocess communication between applications, either on the local system or spread in a distributed, TCP/IP based network environment. Once a peer-to-peer connection is established, a socket descriptor is used to uniquely identify the connection. When you connect to Wi-Fi, you are usually given an IP address, and this process is performed by DHCP. The valid IP configuration issue means that something is wrong, and DHCP fails to receive a valid IP address. You can add a valid IP address manually to fix this problem - right-click on Start and select "Network Connections". Private IP Address: These are used inside a network, for example, a home network that is used by tablets, Wi-Fi cameras, wireless printers, and desktop PCs. These types of IP addresses provide a way for devices to communicate with a router and the other devices on the private home network.Private IP addresses can be set manually or assigned automatically by the router. The address it uses is the IP address for your connection. So long, IP address. It was nice while it lasted. When you're at home, an IP address is assigned to your computer by your Internet service provider (think Time Warner Cable, Cox Communications, or AT&T). A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network. It establishes the connection between the local computer and remote computer in a way that the local terminal seems to be a terminal at the remote system. FTP. FTP stands for File Transfer Protocol. It is an internet protocol used for transferring the data, media files from one computer to another computer. Advantages of TCP/IP Find Your Router's IP Address in Windows. RELATED: 10 Useful Windows Commands You Should Know. Your router's IP address is the "Default Gateway" in your network connection information on Windows. If you prefer using the Command Prompt, you can find the default gateway for any connection quickly by using the ipconfig command.

Whether your connection is wireless or wired, you can also find this information by opening the Apple menu, and then heading to System Preferences > Network. Select your network connection, and then click "Advanced." You'll find IP address information on the "TCP/IP" tab and the MAC address on the "Hardware" tab. iPhone and iPad Right-click on the network adapter you want to assign an IP address and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4), then click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server addresses. When you're finished, click OK.

If you're connected to the local network through Wi-Fi, the active IP address will be shown under the "Wireless LAN adapter Wireless Network Connection" section of the ipconfig output. If you're connected by an Ethernet cable, the address will be shown under "Ethernet adapter Local Area Connection." If connected to both networks simultaneously

Find the network connection that you want to have a fixed address. Click the button next to the network connection. For a Wi-Fi connection, the button will be located next to the active network. Select the IPv4 or IPv6 tab and change the Method to Manual. Type in the IP Address and Gateway, as well as the appropriate Netmask. The IP Allow List and the IP Block List each support a maximum of 1273 entries, where an entry is a single IP address, an IP address range, or a Classless InterDomain Routing (CIDR) IP.
