IPv6 Migration: 10 Reasons To Get Moving

You can't afford to put off that IPv6 transition any longer. Here are 10 ways migrating to the updated protocol will benefit your enterprise.


It has been too long

The arguments are all convincing, the infrastructure is basically ready. I just have the feeling that we had the same conversation over and over the past few years, and some people are still reluctance to make the change.

I can only assume that the human condition of resistance to change is the main reason, apart from cost.

Re: It has been too long

All the points are excellent reasons, but I feel that the 10th reason will be the factor that speeds up IPv6 adoption. Security and more importantly, end-to-end point security is becoming a major concern for businesses. I am not exactly sure how a hacker got a password and gained access to iCloud, but if the hacker used a translation layer then, IPv6 will not be ignored anymore. 

Re: It has been too long

Brian, I agree. I'm not sure why we made you click all the way through to the end of the slideshow before you got to security! That will most likely be the deciding factor in most migrations. That and the increasing number of devices for sensor and industrial networks, I bet.

Re: It has been too long

Hello everyone,

@ Susan, thanks for the link.

Some RIR still have IPv4 address available -- this the case of AFRINIC
Also,  many network engineers don't master yet this addressing scheme.

I've studied,learned and praticed IPv6 on differents vendors equipements;( of course i still increase my design skill, because we have too much space that we need efficient planning)  what i can say in all it's the base of the internet future! Many new  tech depends on it; IPv6 is a must !


Re: It has been too long

I've suscribed to "WEEKLY BGP REPORT FOR  AfriNIC v6 PREFIXES", so i receive the percentage of IP address allocated from AfriNIC pool, also the percentage of IP address from AfriNIC pool announced to Internet and the numbers are very very very small (less than 0,5%). I known some new data centers which are designed with both v4 and v6 addresses but the operates only with v4, also same thing with 4G network

I think as long as they will have v4 addresses and things work like they want, they will not decide to move to v6. Some would say IPv4 will dead but  will disappear ?

Re: It has been too long

Jerome, you actually snatched the words from my mouth.

As long as v4 is available, people would prefer to use that and do whatever it takes to use v4 like dual stack, cgnat, nat64 etc etc.

Very rightly said, IPv4 will die but would it disappear? I guess not.

Re: It has been too long

Agreed, a few technologies become obsolete but they still remain present. I have heard of a few POS systems that are still using dial-up as their primary mode of connectivity.

Re: It has been too long

Brian, that's very true, technologies tend to hang around far longer than you expect them to. Even if an environment wants to migrate to IPv6, it is bound to have pockets of IPv4 that persist. The other day I used my credit card to pay for a taxi fare and the driver used one of those old credit card imprinters with the carbon copy receipt. I haven't seen one of those in a while! 

Re: It has been too long

In my country for example, this year (2014) the IT authorities have decided the migration to IPv6.

So many big institutions, isp, .. have got their prefix and i know some of them which have already  designed the network infrastructure with IPv6 (i mean they are ready for ipv6 but they do not operate into v6). As i said, the step of the design is very very important in the case of IPv6.  I thing many companies are waiting for the ISP.

Re: It has been too long

"Some RIR still have IPv4 address available -- this the case of AFRINIC

There is no doubt in my mind that we won't see a final transition to IPv6 until the entire address pool of IPv4 is depleted.

Re: It has been too long

@Susan, it is great that the best was saved for last. There might be many firms that deploy IPv6 due to the vast amount of addressable space that it enables, but then again, if there are a large number of IP addressable devices in the environment, then securing these open points that can be pinged and communicated with, become even more important.

Re: It has been too long

Pablo, I am afraid you're right. Resistance to change is a huge factor -- just look at all of the users still on Windows XP! I doesn't help matters that even though we keep saying IPv4 addresses are exhausted, IANA magically finds new address pools to release -- this just happened again yesterday. That definitely will keep people dragging their feet. It also doeasn't help that IPv6 is very cumbersome and difficult to learn. They aren't making it easy for us!

Re: It has been too long

"... just look at all of the users still on Windows XP!"

Susan, I'm afraid I'm one of them! but I'm determined to change that this year.. to ChromeOS!

We have been using IPv4, DNS and NAT for so long that learning a new system looks extremely complicated, mostly because it doesn't always relate to the old one.

Re: It has been too long

I remember to read articles about IPv4 address space getting over and recommendation to migrate to IPv6 when I started my career as early as 1998 and the fact remains that there are still few million IPv4 addresses are available.

Probably this is one of the reason people believed that there is still time.

Ipv6 -- Reasons


Great article. Very clear, precise and excellent summary!

Advertise it on other social network will be interesting.


Say yes to IPv6!

OK, I know several of our bloggers and community members DO work with IPv6. Can you tell us why your network has made the migration, or if it uses IPv6 in certain cases? 

Governments are setting a poor example

It doesn't help that world governments have been so slow -- and hypocritical -- in implementing IPv6 migration.

In the US, for example, the federal government was required to complete full migration by June 30, 2008.  When that deadline was missed, it set a new one for itself: 2010.  When that year came around, it pushed it off until the end of 2014.

And we're still waiting.

Similar situations have been happening at the state level, as well as in other countries, such as in the UK and throughout Africa.

Re: Governments are setting a poor example

I would like to know how many of the big IT companies have fully migrated to IPv6.  I'm willing to bet that most of them, even big names like Cisco are probably still relying on IPv4 for some of their systems.

If the big tech companies haven't fully switched, I can't see how they would be able to create the necessary momentum.

Re: Governments are setting a poor example

Indeed, AbeG, the response by many major enterprises to the IPv4 crisis was not to expeditiously migrate to IPv6 but rather to buy up and hoard as much IPv4 space as possible.

I'm guessing the Cubs stand to win a World Series or two before we see full IPv6 migration.

Re: Governments are setting a poor example

Perhaps an Ice Bucket challenge for IPv6 is in order.  Maybe we could start a rumor about it :)

Re: Governments are setting a poor example

@AbeG: At a recent conference I attended, the advice being evangelized from the resident experts was to encourage and foster IPv6 adoption by demonstrating how great it is and the ROI at stake rather than taking the fear route.  Indeed, the enterprise is increasingly becoming both the cloud enterprise and the big data enterprise, and both of those types of enterprise are quickly becoming the IoT enterprise because of the myriad benefits for interconnectivity and big data accessibility and analytics that IoT offers -- and IoT DEPENDS upon IPv6 migration (especially if Cisco's prediction that we'll have over 50 billion devices connected by the 2020s is apt -- considering that there are only about 4.3 billion IPv4 addresses).

So, yeah, I'd use those talking points instead.  ;)

Re: Governments are setting a poor example

@Joe.  When companies say things along the lines of "...we'll have over 50 billion devices connected by the 2020s is apt -- considering that there are only about 4.3 billion IPv4 addresses".  Isn't it a bit misleading?

Those 50 billion devices are likely to be sitting behind a firewall and relying on NAT.  I'm very much in favor of accelerating the transition to IPv6, but despite that, I think it's going to be a hard argument to make with most businesses.  

Personally, I think that this is something where consumers actually stand a better chance of leading the way.  Getting most consumers switched over to IPv6 should be relatively painless at this point.  And while we're at it, maybe we could turn up the fire on the transition to HD public radio.

Re: Governments are setting a poor example

That's an interesting point, AbeG.  We're in an age in which enterprise technology is flowing upwards from consumers to the enterprise -- from choice of smartphone and ubiquity of tablets to IoT technological developments.  You may well be right that this is an area where -- if not consumers themselves -- the consumer market is in an excellent position to take a leading role in the IPv6 transition.
