100% IPv4 Utilization

by | March 7, 2012

100% IPv4 Utilization is a short term solution. We outline the problems encountered by those who have have forged head with insufficient research. 6Connect makes transitions an opportunity for improvement, instead of an invitation to crisis. There has been increasing interest from enterprises seeking IPAM / DNS tools. The trend is becoming clear – IPv6 adoption and the need for automation software & tools will follow the Internet ecosystem’s supply chain starting with service providers (consisting of ISPs, I/PaaS and ASPs) then content providers, then enterprises – with demand ultimately driven by consumers increasing apatite for connected devices and services.

It has given us a chance to revisit and reflect thru many TCP/IP protocol standards – why they were implemented in the first place, how they eventually were used and then what that would mean in the transition to IPv6 (in the context of not just service providers but enterprises as well). IPv4 address space utilization has also, ironically, become the primary driver for enterprises to seek automation tools.

There are now an overwhelming number of enterprises put their need for IPv4 scanning and assigning as the only requirement of IPAM/DNS & DHCP.

Why this is a problem now

IPv4 is nearly exhausted – while there are remaining addresses to be had, prices will continue to increase as demand increases over dwindling supply.

Error rates found in the ‘typical’ enterprise is high. So much so that a migration to IPv6 will be disastrous without first normalizing data in the v4 network.

IP Address Management is the first real step to gaining control over the network to be able to gain true and accurate network visibility – but most enterprises have spreadsheets as their IPAM tool.

During next few years, some address space will become available for purchase but admins will still need to justify with proof (80% utilization) to the RIRs as Microsoft recently discovered with ARIN.

Mistakes we are seeing

Admins are finding solutions to meet “internal policies/procedures” and not establishing IPAM based procedures and protocols. The two most common mistakes we are seeing are –

1) Not thinking about IPv6 at all.

2) Using RFC 1918 yet not thinking about how that goes away in IPv6.


Seek an IPAM solution as the first step in IP reclamation, data normalization, and network discovery. You don’t know what you can’t see.

Poor stewardship of IP addresses is not an admin’s fault, but lack of preparation without an IPAM tool will set the stage for a potentially difficult series of challenges as v6 approaches.

Waiting for v6 to come as the impetus for change is a recipe for potentially significant risk exposure. Implementing an IPAM tool today to manage v4 space creates a platform for the inevitable “sea change” coming, while providing much better management of current network space.

“We decided to move our rather complex IP address and DHCP management process to ProVision and it has worked out great for us!! The team at 6connect were very flexible and went above and beyond to accommodate our requirements and helped to make the migration as smooth and hitch free as possible. Kudos to the team @ 6connect!”

Head of R&D

“We are excited to be partnering with 6connect to leverage their technology and talent. We particularly admire their long-standing IPv6 contributions and their ability to service and support customers in this area, some who are the largest service provider in the world. The 6connect executive leadership team and technical team are great to work with and we look forward to many partnered projects to help customers address their Cloud, IoT and Security needs with IPv6. Automation, workflow and orchestration are critical to the success of most of these projects and 6connect is well positioned to help our mutual customers in those areas.”

Ed Horley
Co-Founder & CEO

“Enterprises can struggle managing purposefully segmented DDI architectures with any agility. Our partnership with 6connect empowers customers with complex infrastructures to move faster to service the business while consolidating visibility and control over their estate.”

Andrew Wertkin
Chief Strategy Officer,

“6connect’s approach to automation addresses quite a few challenges with physical and virtual networks – how to improve the agility of your current network infrastructure without sacrificing reliability and adoption of future network technologies.”

Pär Lange
Investment Director

“A customer is looking for an integrated solution from a single vendor for both IPAM and DNS. Through the 6connect reseller program, Secure64 is able to offer the most secure DNS solutions married to a unique combination of IPAM and resource provisioning that customers want. It’s a marriage made in heaven.”

Mark Beckett
VP of Marketing

“A huge benefit of working with the 6connect team is that they devoted a lot of resources to get our products integrated so we had the turnkey solution that we could take to market. It was very easy to work with their team to get product integrated and successfully launched.”
