What info is provided by My IP Address?TCPView for Windows
TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections...
...displays the list of all currently opened TCP/IP and UDP ports on your local computer. For each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it.

Computers can use static or dynamic IP addresses. A static IP address is a number assigned to a computer by an Internet service provider (ISP) and intended to be its permanent address on the Internet. Thus it will not change.
However, there are not enough IP numbers for each computer so many ISPs limit the number of static IP addresses they assign and utilize a pool of IP addresses instead. The ISP will temporarily assign a dynamic IP address automatically to a requesting Dynamic Host Configuration Protocol (DHCP) computer from this pool of addresses and it will change each time you connect to the Internet. When you disconnect from the Internet, the temporary dynamic IP address is returned to the IP address pool so it can be assigned to someone else. When you reconnect, you are then assigned a different dynamic IP address from those available in the pool.
Hackers use "port scanning
" to search for vulnerable computers with open ports using IP addresses or a group of random IP address ranges. Botnets and Zombie computers
scour the net and will randomly scan a block of IP addresses. These infected computers are searching for "vulnerable ports
" and make repeated attempts to access them.
