However, because of the growth of the internet and the predicted depletion of available addresses, a new version of IPv6 using 128 bits for the for the address, was develop in 1995. IPv6 was standardized RFC 2460 in 1998 and its deployment has been ongoing since mid-2000s. IP address are usually written and displayed in human-readable notations , such as 172.16.251.1 (IPv4)and 2001:2b8:0:1234:0:567:8:1 (IPv6).
