IPv4 Datagram format:

1. The IPv4 header size is 20 to 60 bytes long .
2. The IPV4 header field formerly known as the services type field in now
called the differentiated services field .
3. In IPv4, which field or bit value unambiguously identifies the datagram as
a fragment?
Ans: Fragment offset = 1000
4. In IPv4, an HLEN value of decimal 10 means 40 byes of header

IPv4 IPv6
Addresses are 32 bits (4 bytes) long. Addresses are 128 bits (416 bytes) long.
Both routers & sending host fragment the
packets.
Routers don’t fragment the packets but sending host
fragment the packets. Packetflow identification are
Available and uses flow label field in the header
Header includes a checksum. Header doesn’t includes a checksum.
Classes of addressing are A, B, C, D, E. Classes of addressing are unicast, anycast, multicast.
Configure either manually or through
DHCP.
Doesn’t require manual configuration. Auto and
renumbering address configuration
Must support a 576 byte packet size. Must support 1208 byte packet size.
IPv4 address uses the dot-decimal
notation.
IPv6 address are represented in a hexadecimal,
colon-separated notation.
Not suitable for mobile networks. IPv6 is better suited to mobile networks.
Address space is small (232). Larger address space (2128).
Internet protocol security(IPSec) is
mandatory in this.
IPSec is optional.
An IP address is made up of 4 bytes of
information expressed as 4 number
between 0 & 255 shown separated by
periods. e.g.- 238.17.159.4
An IPv6 address is represented by 8 group of 16 bit
hexadecimal values separated by colons (:).
