Top Six Misconceptions About IPv6 Adoption

Monday, February 28, 2011



Carolyn Duffy Marsan has published a fantastic article that addresses some of the biggest misconceptions about the implementation of the IPv6 protocol  and the slow and painful demise of IPv4.

Though the new 128 bit web addressing system has been in development for nearly fifteen years, many executives do not understand the fundamentals of the change over from the current 32 bit system and the possible implications for their company.

Marsan outlines some sound information in the article, and dispels some rumors myths surrounding the evolution of the device addressing system.

Excerpts from Marsan's article are as follows:

1. The Internet still has plenty of IPv4 addresses: Over the next few months, it will become increasingly difficult for mobile and broadband carriers with fast-growing networks to acquire the blocks of contiguous IPv4 address space that they need to build out their networks. Some carriers are predicting massive IPv4 address shortages this year...

2. My company doesn't need to adopt IPv6 yet: John Curran, president and CEO of the American Registry for Internet Numbers (ARIN), says all companies that do business over the Internet should support IPv6 on their public-facing Web servers and Web services by Jan. 1, 2012 or risk losing potential customers...

3. A lucky Internet user will get the last IPv4 address: One lucky Internet user won't get the last IPv4 address is that carriers are likely to share these increasingly scarce resources among multiple users. So even if you could figure out who got the last IPv4 address from a particular carrier in a particular region, the address would likely be shared among multiple users...

4. A black market will emerge for IPv4 addresses: Raul Echeberria, chairman of the Number Resource Organization, which represents the five regional Internet registries, admits that a black market for IPv4 addresses is a possibility but says that he is not sure it will evolve because of the existing rules for IPv4 address transfers. But he adds that the value of IPv4 addresses will decline as network operators adopt IPv6, making this black market less attractive...

5. IPv6 is more secure than IPv4: "It's a myth that IPv6 is more secure than IPv4," says Qing Li, chief scientist for Blue Coat Systems, which supports IPv6 in its network appliances. "IPv6 was designed to facilitate the implementation of IPsec better, it allows IPsec to operate better, but that's just a facility... It doesn't mean that IPv6 by itself is more secure"...

6. IPv6 will make the Internet simpler: IPv6 offers the promise of end-to-end communications with the removal of network address translation (NAT) devices and other middle boxes that were necessary to extend the life of IPv4's limited addressing scheme. But in reality, network operators are going to have to run IPv6 and IPv4 side by side for years - if not decades - to come. This lengthy co-existence of the two protocols is going to make network management more complex for the foreseeable future...
