Why does IPv6 use separate extension headers instead of fields in a single fixed header?

IPv6 includes an improved option mechanism over IPv4. IPv6 options are placed
in separate extension headers that are located between the IPv6 header and the
transport-layer header in a packet. Most IPv6 extension headers are not examined or processed by any router along a packet's delivery path until it arrives at its final
destination. This facilitates a major improvement in router performance for packets
containing options

Why is having a first and last name field in Microsoft Access better?
It is always better to have them as separate fields. It is very common to sort on last names and if there was a field which held the first name and last name in one field instead of two separate fields, it would not be possible to do that. If you take a phone book, the entries are always sorted by the last name. So in a properly designed database the first name and last name should always be separate fields.
Contrast the IPv4 and the IPv6 header fields?
Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing. Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.
