1. Binary Lesson 4Slash Notation

2. A Single IPv6 Address 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

3. A Range of IPv6 Address 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: fe80:0000:0000:0000:0000:0000:0000:0000 fe80:0000:0000:0000:0000:0000:0000:0001 fe80:0000:0000:0000:ffff:0000:0000:0000 fe80:0000:0000:0000:ffff:ffff:ffff:ffff ---- ---- ---- ---- 64 bits

4. A Range of IPv6 Address fe80::/16 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: fe80:0000:0000:0000:0000:0000:0000:0000 fe80:0000:0000:0000:0000:0000:0000:0001 fe80:ffff:0000:0000:0000:0000:0000:0000 fe80:ffff:ffff:ffff:ffff:ffff:ffff:ffff ---- 16 bits

5. A Range of IPv6 Address fe80::/8 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: fe80:0000:0000:0000:0000:0000:0000:0000 fe80:ffff:ffff:ffff:ffff:ffff:ffff:ffff fe8f:ffff:ffff:ffff:ffff:ffff:ffff:ffff feff:ffff:ffff:ffff:ffff:ffff:ffff:ffff -- 8 bits

6. A Single IPv6 Address • fe80::462a:60ff:fef6:0278/128 • The /128 means all 128 bits are fixed fe80:0000:0000:0000:462a:60ff:fef6:0278 ---- ---- ---- ---- ---- ---- ---- ---- 128 bits

7. The Unspecified IPv6 Address • ::/0 • The /0 means no bits are fixed • All 128 bits can vary • This range includes all addresses, including 0000:0000:0000:0000:0000:0000:0000:0000 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 0 bits
