Nevertheless the Internet has grown in a way nobody expected 20 years ago. Despite all

our cool tricks like VLSM and NAT/PAT we needed more IP addresses and so IPv6 was born.

Internet Protocol version 6 (IPv6) is the latest version

Protocol (IP), the communications protocol that provid

and location system for computers on networks and routhe Internet. IPv6 was developed by the Internet Engin

(IETF) to deal with the long-anticipated problem of IP

exhaustion.

IPv4 and IPv6 are not compatible with each other so many protocols have been updated

or replaced to work with IPv6, here are some examples:

OSPF has been upgraded from version 2 (IPv4) to version 3 (IPv6).

ICMP has been upgraded to ICMP version 6.

ARP has been replaced with NDP (Neighbor Discovery Protocol).

What about routing? Is there a difference between IPv4 and IPv6?

Lets look at the routing

options: Static Routing

RIP RIPng

OSPF OSPFv3

BGPMP-BGP4

EIGRP

Lets take a look at the format of an IPv6 address:

2041:0000:140F:0000:0000:0000:875B:131B

Using hexadecimal helps to make our addresses sh

typing in an IPv6 address is still a lot of work.

To help us out, its possible to make IPv6 addresses

Original: 2041:0000:140F:0000:0000:0000:875B

Short: 2041:0000:140F::875B:131B

Shorter: 2041:0:140F::875B:131B

RULES :

A string of zeroes can be removed leaving only

can only do this once.

4 zeroes can be removed leaving only a single ze

Leading zeroes can be removed within a block.

RULE 1 : A string of zeroes can be removed leaving only a colon (::). You can only do this once

Original : 2041:0000:140F:0000:0000:0000:875B:131BShort : 2041:0:140F::875B:131B

RULE 2 : 4 zeroes can be removed leaving only a single zero.

RULE 3 : Leading zeroes can be removed within a block.

IPv4 addresses have a subnet mask but instead of typing something like 255.255.255.0 we use apref

is an example of an IPv6 prefix:

2001:1234:5678:1234:5678:ABCD:EF12:1234/64

2001:1234:5678:1234 5678:ABC
