this system‚ known as IPv4‚ is still in use today. However‚ due to the enormous growth of the Internet and the predicted depletion of available addresses‚ a new version IPv6‚ using 128 bits for the address‚ was developed in 1995. IPv6 was standardized as RFC 2460 in 1998‚ and its deployment has been ongoing since the mid-2000s. IP addresses are binary numbers‚ but they are usually stored in text files and displayed in human-readable notations‚ such as 172.16.254.1 (for IPv4)‚ and 2001:db8:0:1234:0:567:8:1
