- IPv4 exhaustion
- IPv6 addressed are 128-bits in size, offering a hugh amount of addresses. (IPv4 being 32-bits)
- IPv6 doesn’t use broadcasts
- NAT will be a thing of the past. NAT is also a hinderance to progression.
- IPv6 was designed with route aggregation/summarisation in mind.
- IPv6 offers greater security capabilities
- DHCP is still available, but IPv6 nodes can assign themselves an address without the help of a DHCP server via autoconfiguration.
- QoS capabilities with IPv6 are far greater, due to many more values within the IPv6 header.
IPv6 + IPv4 Headers
There are eight header fields in IPv6:
- version – This is set to “6” in IPv6.
- traffic class – In IPv4, this was the Type Of Service (TOS) field. The “traffic class” name comes from this field’s ability to allow us to assign levels of importance to a packet via QoS.
- flow label – No equivalent in IPv4, this field…
