IPv6 Question
Hello folks -
Studying for the Network+ exam. I have a question about Stateless Autoconfiguration (EUI-64). Within my Network+ book, it states it looks at the 7th bit of the U/L to change it into a link-local address?
10 = Universal Unique
00 = Locally Unique
For example -
Original MAC Address: 0060:D673:1987
Padded with FFEE: 0260:d6FF:FE73:1987
How does the 2 get in the beginning of the MAC after FFFE gets added? I can't understand the book's explanation.

Convert it to binary and flip the 7th bit . what is the outcome?
What portion is converted to Binary? -

IPv4 was the first version of internet protocol. There are just over 4 billion IPv4 addresses. IPv6 is newer numbering system to replace IPv4. The major difference between IPv4 and IPv6 is the number of IP addresses.

There's a lot more differences between IPv4 and IPv6 than just the size of the address space: https://en.wikipedia.org/wiki/IPv6#Comparison_with_IPv4
