Understanding IPv6 Address Length
How many bits long is a standard IPv6 address?
Attempts:
2 left
💡 Hint
Think about how IPv6 expands the address space compared to IPv4.
✗ Incorrect
An IPv6 address is 128 bits long, which is four times longer than the 32-bit IPv4 address. This allows for a much larger number of unique addresses.

IPv6 Address Representation
Which of the following is the correct way to write an IPv6 address?
Attempts:
2 left
💡 Hint
IPv6 addresses use colons to separate groups of hexadecimal digits.
✗ Incorrect
IPv6 addresses are written as eight groups of four hexadecimal digits separated by colons. The other options use incorrect separators or formats.

Compressed IPv6 Address Interpretation
What is the expanded form of the IPv6 address
2001:db8::1?Attempts:
2 left
💡 Hint
The double colon (::) replaces consecutive groups of zeros.
✗ Incorrect
The double colon (::) in IPv6 addresses means one or more groups of 16-bit zeros. Here, it replaces six groups of zeros, making the full address eight groups long.
❓ Comparison

IPv4 vs IPv6 Address Space
Compared to IPv4, how much larger is the IPv6 address space?
Attempts:
2 left
💡 Hint
IPv4 addresses are 32 bits; IPv6 addresses are 128 bits.
✗ Incorrect
IPv6 addresses are 128 bits long, while IPv4 addresses are 32 bits. The difference is 96 bits, so the IPv6 space is 2^96 times larger than IPv4.

IPv6 Address Types Identification
Given the IPv6 address
ff02::1, what type of address is this?Attempts:
2 left
💡 Hint
IPv6 multicast addresses start with 'ff'.
✗ Incorrect
IPv6 multicast addresses always start with the prefix 'ff'. The address ff02::1 is a multicast address used to reach all nodes on the local link.
