  1. TCP/IP and NetworkingFundamentals Hamidreza Talebi- TCP/IP

  2. Fundamentals of IPv6 Hamidreza Talebi- TCP/IP

  3. Contents • Disadvantages of IPv4 • IPv6 Solutions • IPv6 Addressing • Types of IPv6 Addresses Hamidreza Talebi- TCP/IP

  4. Disadvantages of IPv4 • Not Enough Addresses • Cluttered the Internet Routing Tables • Difficult to Configure • Security Was Optional Hamidreza Talebi- TCP/IP

  5. IPv6 Solutions • Plenty of Addresses - 3.4 x 1038 • Simplified the Internet Routing Tables • Easy and Automated Configuration • Security is Required Hamidreza Talebi- TCP/IP

  6. IPv6 Addressing • • 128 bits long • 1111111010000000000000000000000000000000000000000000000000000000 • 0000010111101110000000001111111100000010001110000100011110110001 • • Displayed in 16 bit hexadecimal blocks • FE80:0000:0000:0000:05EE:00FF:0238:47B1 • • Simplify by suppressing the leading 0’s • FE80:0:0:0:5EE:FF:238:47B1 • • Further compress by expressing a single • contiguous set of 0 blocks into “::” • FE80::5EE:FF:238:47B1 Hamidreza Talebi- TCP/IP

  7. Types of IPv6 Addresses • • Unicast (One to One) • – Global Addresses • – Link-Local Addresses - FE80 • – Unique Local Addresses - FC or FD • • Multicast (One to Many) • • Anycast (One to One of Many) Hamidreza Talebi- TCP/IP

  8. Summary • The way IPv6 solves the problems we are facing with IPv4. • What an IPv6 address looks like. Hamidreza Talebi- TCP/IP
