Good for us in the long run but no immediate sugar rush from deploying it"
Nicole Wajer, Cisco
IPv6 has been developed in 1998 to address the shortage of IP addresses available under Ipv4, yet despite its efficiency and security advantages, adoption is still slow.
The current situation with very slow IPv6 adoption ( about 26% according to Google) split IT community into two camps: the first one thinks that IPv6 protocol is the only way to avoid running out of IPs (the last batch will be given out in the August of this year). And the other ones say that technology has no future and alternative should be developed.
What are the arguments against IPv6?
- in this article, the authors concluded that IPv6 adoption is so slow because it's already outdated and is not capable to work good in a mobile environment
- in some researches, there is a statement that in some counties IPv4 works better and the packages deliver faster than IPv6
- and last but not least - many companies just don't want to update -in other words to invest in their IT infrastructure now.
- when IPv4 deficit will increase it would be cheaper to update everything on IPv6 that to buy new IPv4 addresses
- IPv6 has no broadcast messages. A broadcast is a message that is sent to all devices on the same network. This means that all devices have to take the time to accept and interpret the broadcast message, even though the broadcast message is meant for only one device. Because IPv6 has no broadcast messages, it saves bandwidth, time and processing power
- Reduce reliance on NAT
- Better geolocation addressing
In there any alternatives to all this mess?
While the situation with IPv4 to IPv6 transition is not settled yet, there are some scientist and engineers who propose the alternatives:
- Named Data Networking (NDN). they propose to replace IPv4 address with something like this /ucla/videos/demo.mpg/1/3 . As advances of new technology authors name built-in encryption, no limitation of address quantity and no need to develop additional addresses to local networks
- Recursive Internetwork Architecture (RINA)
What about you? Do you think that IPv6 has a future? Is it expensive to buy IPv4 address now? Do you have an approved plan on IPv6 transition?
