Table 4-2. IPv4 Header Fields and Corresponding IPv6 Equivalents
IPv4 Header Field IPv6 Header Field
---------------------------------------------------------------
Version Same field but with a different version number.
Internet Header Length Removed in IPv6.IPv6 does not include a Header Length field because the IPv6 header is always a fixed length of 40 bytes. Each extension header is either a fixed length or indicates its own length.
Type of Service Replaced by the IPv6 Traffic Class field.
Total Length Replaced by the IPv6 Payload Length field, which indicates only the size of the payload.
Identification Flags Fragment Offset
Removed in IPv6. Fragmentation information is not included in the IPv6 header. It is contained in a Fragment extension header.
Time-to-Live Replaced by the IPv6 Hop Limit field.
Protocol Replaced by the IPv6 Next Header field.
Header Checksum Removed in IPv6. The link layer has a checksum that performs bit-level error detection for the entire IPv6 packet.
Source Address The field is the same except that IPv6 addresses are 128 bits in length.
Destination Address The field is the same except that IPv6 addresses are 128 bits in length.
Options Removed in IPv6. IPv6 extension headers replace IPv4 options.
The one new field in the IPv6 header that is not included in the IPv4 header is the Flow Label field.
Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network. Unlike similar protocols such as 6to4, it can perform its function even from behind network address translation (NAT) devices such as home routers.
