Today day is the World IPv6 day the day when many well known companies will turn on IPv6 on their web-sites and email servers for the first time.

Here at Erion, we have been running IPv6 for nearly 15 years and so we have no need to turn anything on today, it will be service as normal. For a long time we have successfully run all our Internet facing services over IPv6 and most of our internal services over IPv6. This has been a great success and we have experienced very few problems. In the main, the deployment of IPv6 was easy.

However, as the world’s leading IPv6 training company, you would expect us to get the deployment of IPv6 right.

For others it can be more challenging. It is easy to turn on IPv6 services but there are many differences between IPv4 and IPv6 that can lead to problems. Many assume that IPv6 is the same as IPv6, just with longer addresses. This is not the case. IPv6 has many differences, for example use of multicast, auto-configuration, transition mechanisms and support for new features such as mobility. In addition, the large number of Transition Mechanisms bring a great deal of additional complexity to IPv6. Therefore, when deploying IPv6 is it is important to understand the differences from IPv4 and learn the about the pitfalls and how to avoid them.

To all those who are enabling IPv6 for the first time, we wish them a successful World IPv6 day!

At this year’s SambaXP, Erion’s David Holder gave a comprehensive presentation on how to deploy Samba in IPv6 networks. The presentation, Deploying Samba in IPv6 Networks, covered how to configure IPv6 in a network consisting of Samba Unix/Linux servers and Windows clients/servers all running IPv6.

The presentation highlights the key differences between IPv6 and IPv4 that must be considered when deploying Windows networking using Samba. These include the correct configuration of the right kinds of IPv6 addresses, the configuraton of StateLess Address AutoConfiguration (SLAAC), the optional configuration of DHCPv6, the configuration of IPv6 enabled DNS and finally the configuration and operation of IPv6 enabled Samba.

Erion has a long history of working with Unix/Linux and Windows integration and in particular with the Samba Team on IPv6 enabling Samba. Further information can be found on our blog under Samba.

3rd February 2011 is the day that IANA (The Internet Assigned Numbers Authority) finally assigned the last five /8 blocks (slash-eight blocks), one to each Regional Internet Registry (RIR).

Now the IPv4 Internet only has the stock of IPv4 addresses held by the regional registrars and Internet Service Provides (ISPs) to keep it going.

If you have not yet implemented or migrated to IPv6 then now is the time to do so. World-wide the move to IPv6 is rapidly gaining momentum as a result of the exhaustion of the IPv4 address pool. IPv6 is the only solution to the Internet address shortage. It is well developed and well understood. There are many good reasons to implement IPv6 and few down sides.

As a first stage in implementing IPv6, it is crucial that you train your staff. IPv6 is not simply IPv4 with longer addresses. There are many more differences between IPv6 and IPv4.

The differences do indeed start with changes to addresses, but they are not simply in the size of the addresses but also the types of addresses, their attributes and the way they are used. In addition to this, IPv6 includes many new features and makes better use of some of the features found in IPv4. For example, in IPv6 ICMPv6 is used for many critical functions. In IPv4, it is often possible to ignore ICMP, in IPv6 you cannot. This is one small example of the way in which IPv6 is different from IPv4. Others include, use of mulitcast, mobility, IPSec, QoS and the huge area of transitiom mechanisms.

So IPv6 education is critical.

Erion has been providing IPv6 services for over twelve years. As a part of this we provide the world’s most comprehensive and well-developed IPv6 training courses. Erion’s IPv6 training covers all aspects of IPv6, for all audiences, across all major platforms and operating systems. Erion’s certified IPv6 trainers and IPv6 training courses represent the best in the industry. Our customers include many of the world’s leading IT names, for example, Alcatel-Lucent, Arbor Networks, Atos Origins, BAA, BT, Cisco, Ericsson, France Telecom, HP, IBM, The International Telecommunications Union, Microsoft, Orange and Research in Motion.

IANA (the Internet Assigned Numbers Authority) has just allocated two /8 blocks (39 and 107) to APNIC (the regional Internet registry for Asia Pacific). The remaining five blocks will now be allocated, one per regional registrar.

This allocatation means that the pool of IPv4 addresses is effectively empty. After the allocatation of the remaining five blocks the five regional registrars (AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC) will no longer be able to obtain any additional IPv4 addresses. This means that once their customers (ISPs, LIRs and large enterprises) use their remaining stock of IPv4 addresses there will be no further addresses to assign to Internet users.

The solution is IPv6. The IPv6 address space in unimaginably large and is unlikely to be exhausted for generations, if ever. IPv6 not only solves the IP address problem it also brings with it many improvements and new features that have the potential to significantly change the way we use the Internet.

If you are not already using IPv6 (and you probably have IPv6 traffic on your network even if you don’t think you have) then now is the time to begin.

Erion is the world’s leading IPv6 training organisation (http://www.erion.co.uk). We have been providing IPv6 training and IPv6 consultancy services for over twelve years. Our IPv6 training portfolio is the world’s largest, covering all aspects of IPv6 for a wide range of audiences on all major operating systems and platforms.

Erion was a case study at the EU’s workshop on IPv6 training in Ghent, Belgium earlier this week. At the event, Erion’s David Holder presented the opening talk.

In his presentation, David set out to the lessons learned by Erion in over 12 years of providing IPv6 training. He described how Erion set about becoming the world’s leading IPv6 training company with the world’s most comprehensive set of IPv6 training courses and how they came to achieve this.

His presentation slides can be found here, Erion Case Study of World-Leading IPv6 Training Company at EU IPv6 Curricula Day Presentation. Please contact us if you have any questions.

Today four IPv4 address blocks (/8’s) were allocated by IANA. This leaves only seven blocks to be allocated to the Regional Internet Registries (RIRs). RIR policy states that when the central pool reaches five blocks, the remaining blocks will all be immediately allocated. This means that the final allocation is likely to be to APNIC (Asia Pacific Network Information Center) in January 2011. APNIC’s usual allocation is due in two weeks but will almost certainly be delayed until the New Year.

This means that IPv4 exhaustion will finally be reached in early 2011, just as was predicted. From then on everyone who requires IPv4 addresses will only be able to use exisiting stocks. RIRs have a stock of IPv4 addresses that will last for a number of months. Some ISPs also have stocks that will keep them going for several months.  If you are unfortunate enough to require IPv4 addresses and your local RIRs and ISPs have exausted their stock, then you will no longer be able to get any public IPv4 addresses.

Public IPv4 addresses are necessary to connect to the global Internet. Whilst large numbers of networks use “Intranet” addresses, internally these cannot be connected directly to the Internet,  so at some point public IPv4 addresses are essential. Furthermore, many applications and services must use public IPv4 addresses. This means that if you cannot get public IPv4 addresses for your organisation, you could face serious problems for your Internet connectivity and Internet services.

The long term solution is IPv6. IPv6 has almost limitless address space and is available in all modern operating systems and network equipment. There is no doubt that the exhaustion of IPv4 addresses will result in a rush to migrate to IPv6.
