IPAM

We've just published a free online IPv6 subnet calculator for your use and enjoyment. For the uninitiated, a subnet is a subdivision or allocation of a larger address block. Subnetting is necessary to enable an organization to carve up the address block received from its ISP into subdivisions across the organization in order to provide IP address capacity to end devices requiring IP network access. In many enterprises, the subnetting process involves tiers or layers to better map to the organization's routing structure, security policies, applications' routing requirements, or other reasons. Thus in the simplest case, an organization choosing to use the private 10.0.0.0/8 space, they may choose to allocate bits 9-16 to the top layer of its address hierarchy. This would yield 256 subnets, starting from 10.0.0.0/16, 10.1.0.0/16, 10.2.0.0/16, on up to 10.255.0.0/16. Each /16 could in turn be further subdivided using bits 17-24 to create 256 subnets for each of the 256 /16 blo...

As we have done several times over the years, we are planning another webinar series offering educational material regarding IPAM technologies including IPv6, DNSSEC and IDNA. The full webinar lineup , dates and times, and brief synopses are posted on the BT Diamond IP website. Register for any number of topics you're interested in. When planning such a series, we certainly have no shortage of topic ideas. IPv6 as always remains of high interest from the Internet community at large. We ran an intensive 5-webinar IPv6 series about a year ago, and these webinars are still relevant and posted for playback on the BT Diamond IP website. So this time around, I selected three different IPv6 webinar topics.  The first seeks to relate IPv6 to "managers," which yes as the title unfortunately implies, is somewhat "dumbed down" technically in terms of describing IPv6, but it also includes topics related to how IPv6 can impact one's business. I'll discuss the...

It's been a few months since I've posted due to the urgency to finish my new IPv6 book, a death in the family and a period of abnormally onerous work requirements (always getting in the way!). My new book, co-authored with Michael Dooley is entitled, IPv6 Deployment and Management, ISBN-10: 1118387291/ISBN-13:978-1118387207, and will be available within the month. Mike and I were motivated to write this book given the myriad questions we received from customers, prospects, and acquaintances about how to go about IPv6 deployment. Certainly having worked with IPv4 and IPv6 from an IPAM perspective for several years, we were able to share our experiences. However, there's much more to deploying IPv6 than managing the IPv4-IPv6 address space! So we set out to learn about the broader aspects of IPv6 deployment thanks to extensive research and interaction with some of our colleagues, and we discovered that it touches every aspect of the IP network. And given that I've never...
