IPv4Networking Terms

IPv4 is short for Internet Protocol Version 4, and is the fourth revision of the Internet Protocol. In basic terms, it is the technology that allows us to connect our devices to the internet. Through this technology, IP addresses are used to identify devices on a network through an addressing system. IPv4 supports 32-bit addresses, which translates into ^32 IP addresses in total — approximately 4.29 billion. Although this is a huge number, the internet is actually running out of IP addresses—that's where IPv6 comes in.
