Questions & Step-by-Step Solutions

What is the size of an IPv6 address?
Correct Answer: 128 bits
  • Step 1: Understand what an IPv6 address is. It is a type of internet address used to identify devices on a network.
  • Step 2: Know that an IPv6 address is made up of bits, which are the smallest units of data in computing.
  • Step 3: Learn that an IPv6 address is 128 bits long. This means it has 128 individual bits.
  • Step 4: Compare this to IPv4 addresses, which are only 32 bits long. This shows that IPv6 can support many more unique addresses.
  • Step 5: Realize that having more bits means more possible combinations, allowing for a larger number of unique addresses.
