IPv 6 What is IPv 6 Disadvantages Why replace IPv 4 with IPv 6 Why are we still using IPv 4 and when will we switch

What is IPv 6 Scalability IPv 6 has 128 -bit address space compared to

What is IPv 6 Scalability IPv 6 has 128 -bit address space compared to IPv 4's 32 -bit address space 655, 570, 793, 348, 866, 943, 898, 599 vs 4, 300, 000 avalible adresses (estimated 6. 7 billion people on earth) Security It includes encryption of packets and authentication of the sender of packets Consideration to realtimeness To implement better support for realtime traffic, IPv 6 includes flowlabel to utilize QOS Plug and play Most hosts can be configured automatically Clearer spec and optimization Removes minor flaws/obsolete items of IPv 4

Disadvantages Larger overhead 21 DA: D 3: 0: 2 F 3 B: 02 AA:

Disadvantages Larger overhead 21 DA: D 3: 0: 2 F 3 B: 02 AA: FF: FE 28: 9 C 5 A VS 140. 123. 111. 232 But the header can be compressed Hard to set a date/time to switch We can change one step at the time (most recent OS support IPv 6) IPv 6 is already old - why not wait for something even better IPv 6 is still evolving – no “better” standard avalible

Why replace IPv 4 with IPv 6 Larger address space 128 bits long versus

Why replace IPv 4 with IPv 6 Larger address space 128 bits long versus 32 bits in IPv 4 No need for NAT or Subnetting Autoconfiguration Host can be configured automatically when connected Multicast No more avalible IP`s We will proably run out of IP adresses in 2010
