Binary Lesson 4Slash Notation

fe80:0000:0000:0000:462a:60ff:fef6:0278

8 fields, each containing 16 bits

Each field has 4 hexadecimal characters, representing 4 bits each

fe80 = 1111 1110 1000 0000

462a = 0100 0110 0010 1010

fe80::/64

• The number after the slash is how many bits are fixed in the address range

• All the remaining bits are allowed to vary

• This range contains these addresses:
