An IPv6 address is 128 bits long. This is because IPv6 was designed to accommodate the growing number of devices connected to the internet. The increased address space of 128 bits allows for a much larger number of unique IP addresses compared to the previous version, IPv4, which had a 32-bit address space. With 128 bits, IPv6 can support approximately 3.4 x 10^38 unique addresses, ensuring that there are enough addresses for the foreseeable future.Rate this question:
