Internet Protocols Questions
The main difference between IPv4 and IPv6 is the number of available IP addresses. IPv4 uses a 32-bit address format, allowing for approximately 4.3 billion unique addresses. On the other hand, IPv6 uses a 128-bit address format, providing an enormous number of unique addresses, approximately 340 undecillion (3.4 x 10^38). This upgrade was necessary due to the increasing number of devices connected to the internet. Additionally, IPv6 includes improvements in security, auto-configuration, and network-layer features compared to IPv4.
