IP Address
In the most widely installed level of the IP today, an IP address is a 32-bit binary digit

TCP/IP includes your IP address. IP sends your IP address to the IP address obtained by

you are sending a note. A dynamic IP address is an IP address that is automatically
assigned to a client station in a TCP/IP network, typically by a DHCP server.
