19. define IPv6
IPv6willmakeuseof128bitIPaddress.
AnIPv6addressisrepresentedas8
groupsof4hexadecimaldigits,each
grouprepresenting16bits(2octets).
Thegroupsareseparatedbycolons(:).
E.g.-
2001:0db8.85a3:0000:0000:8a2e:0370
:7334

20. difference between IPv4
and IPv6
S.N IPv4 IPv6
1. Addresses are 32 bits(4 bytes)
long.
Addresses are 128 bits(416
bytes) long.
2. Both routers & sendinghost
fragment the packets.
Routers don’t fragment the
packets but sending host
fragmentthe packets.
3. Header includesa checksum. Header doesn’t includes a
checksum.

21. difference between IPv4
and IPv6 cont…
S.N IPv4 IPv6
4. Classesof addressing are A, B, C,
D, E.
Classesof addressing are
unicast, anycast, multicast.
5. Configure either manuallyor
through DHCP.
Doesn’t require manual
configuration.
6. Must support a 576 byte packet
size.
Mustsupport 1208 byte
packet size.

22. difference between IPv4
and IPv6 cont…
S.N IPv4 IPv6
7. IPv4 address uses the dot-
decimal notation.
IPv6address are represented
in a hexadecimal, colon-
separated notation.
8. Not suitablefor mobile
networks.
IPv6is better suited to mobile
networks.
9. Addressspace is small (232).Largeraddress space (2128).

23. difference between IPv4
and IPv6 cont…
S.N IPv4 IPv6
10. Internetprotocol security(IPSec)
is mandatory in this.
IPSecis optional.
11. AnIP 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
by8 group of 16 bit
hexadecimal values separated
by colons (:).
e.g.-
2001:0db8:85a3:0000:0000:8
a2e:0370:7334
