The internet relies on unique addresses to identify and locate devices. These addresses, like your real-world house address called IP addresses. This KB article will explore the two main versions of IP addresses: IPv4 and IPv6, explaining their key differences and addressing the question of speed.<\/p>\n

\"IPv4<\/p>\n

IPv4: The Workhorse of the Early Internet <\/strong><\/p>\n

IPv4, introduced in 1983, has a 32-bit address structure, allowing for a theoretical maximum of around 4.3 billion unique addresses. However, inefficient allocation practices in the past nearly depleted the pool of available IPv4 addresses.<\/p>\n

IPv6: The Future of IP Addressing <\/strong><\/p>\n

IPv6, the next-generation IP address format, introduced in 1999, utilizes a 128-bit address structure capable of supporting 2^128 internet addresses. It was developed to address the limitations of IPv4. This vast address space supports the continued growth of the internet and the ever-increasing number of connected devices.<\/p>\n

Which is faster, IPv4 or IPv6? <\/strong><\/p>\n

IPv6 is faster than IPv4, as IPV6 has NAT, faster routing, and packet processing having high-speed network processing, and it offers:<\/p>\n
