Internet growth is very fast both in terms of internet users in homes, offices, schools, agencies and the rapid development of telecommunications equipment that has begun to incorporate IP into the technology (convergence) in the whole world has led to IPv4 address with 32 bit binary format that is used since the dawn of the internet, can no longer accommodate the needs addressing internet after a period of 20 years or even sooner than that.
Thus the results of research and calculation of an open community of experts from the Internet (The Internet Engineering Task Force, IETF) states. With only a 32 bit address format can only accommodate the needs of:
32
= 2 IPv4 Address
= 4,294,967,296 IPv4 Address
Imagine, the world's current population is 6.5 Billion.
If later masing2 have one computer, one Lapotop (mobile), 1 PDA, 2 Mobile (GSM & CDMA). Then each device needs an IP address to be connected each other.
How many IP is needed to put a 3 Billion people of the world (even of 4 billion IP version 4 is not a whole could be used)?
Shortage of IPv4 addresses is of course going to make progress, especially internet data communications will be disrupted because there are no IPv4 that can be allocated to each computer, other devices will be connected either to the internet or between devices.
Early anticipation is already done with the technology NAT (Network Address Translation) which works by way of interpretation of public IPv4 addresses to multiple private IPv4. So that the public IPv4 address can be used for many devices to be connected to the internet.
The technology is already widespread, but has limitations for interconnection between networks is big enough and different addressing policy, the next gateway needs to address translation, as well as the limitations of Internet protocol development, especially for applications that are directly connected to each other (peer-to-peer) as Peer Games-to-peer and VoIP such as requiring public IPv4 to be working fine.
In 1992 the IETF as an open community of the Internet opened the discussion of experts to address this problem by finding the IP address of the next generation format after IPv4 (IPng, IP Next Generation) which then generates a lot of RFC (request for comments) that document that discusses the stardard protocols, program , procedures and concepts IPv6 internet. After a long deliberation, established in 1995 through RFC2460 IP address IP version 6 as the next generation (IPng) replacement for IP version 4. IPv6 uses 128-bit binary format so that it can accommodate the needs of:
128
= 2 IPv6 Address
= 340,282,366,920,938,463,463,374,607,431,768,211,45 6 IPv6 Address
Development of IPv6 to date has been done by many parties that exist around the world including the Service Provider, Internet Exchange Point, a regional ISP, Military and Universities.
For Indonesia itself has been allocated 61 IPv6 prefix for various organizations,
mobile operator, IXP and the ISP. And based on statistical data from development agencies and providers of SixXS tunnel broker (www.sixxs.net) to date are active:
