IPv6 Buzz

In this week’s episode Ed, Scott, and Tom talk about some of the weird things they’ve seen folks do with IPv6 addresses. IPv6 is different than IPv4 in many ways but the endless supply of IPv6 addresses yields endlessly crazy ways to use them. Topics discussed include: * Creative (and “creative”) use of IPv6 addresses * Is an IPv6 link-local address prefix a /10 or a /64? * Organizations using ULA badly * The use of IPv6 addresses and prefixes (valid and otherwise) in vendor documentation * How the extensibility of the IPv6 protocol leads to other creative approaches to communications Thanks for listening!

In this week’s episode Ed, Scott, Tom, and guest host Greg Ferro talk to Vint Cerf about why the Internet needs IPv6. Vint is Google’s chief Internet evangelist and the co-creator, with Bob Khan, of the Internet Protocol. In the 46 years since, he has continually worked to expand the technologies that facilitate Internet growth while tirelessly advocating for an open and accessible Internet for the benefit of all humanity. Topics discussed include: * Why it’s critical for everyone to adopt IPv6 * The characteristics of IPv6 that make it ideal for the future * The likely life span of the Internet Protocol—both IPv4 and IPv6 * Signs that the open and interconnected nature of the Internet is changing. * Risks that the Internet will fragment along political lines and the potential impacts of that fragmentation Thanks for listening!

In this week’s episode Ed, Scott, and Tom celebrate their 50th episode by talking IPv6 with two guests who need no introduction (but let’s introduce them anyway): Packet Pushers’ very own co-founders Ethan Banks and Greg Ferro! Ethan and Greg grew up in data centers as CCIEs with 20+ years of experience each in production IT environments. They are the primary hosts of the Packet Pushers podcasts, well-known writers, and public speakers and we’re thrilled to have them on the show! Topics discussed include: * Understanding and overcoming objections to new, transformative networking technologies like IPv6 * How vendors often greatly complicate IPv6 adoption * Why service providers have an easier time with IPv6 than enterprises * How cloud adoption is affecting overall IPv6 adoption * Why it’s important to use IPv6 in documentation examples * How IPv6 can represent the most reasonable IT business strategy * How IPv6 could get you a pay raise * Whether or not Ed gets thrown out of enterprise customer meetings for bringing up IPv6

In this week’s episode Ed, Scott, and Tom discuss one of IT networking’s biggest challenges, IP renumbering, and how IPv6 impacts (and is impacted by) it. Anyone who’s ever had to do a significant IPv4 renumbering project knows just how labor intensive and painful this process can be. Will it be easier with IPv6? If so, how and why? Topics discussed include: * What mechanisms exist in IPv6 to make renumbering easier? Is it truly easier to renumber an IPv6 network than an IPv4 one? * What are easy steps an organization can take to make any eventual IPv4 or IPv6 renumbering easier? Why the business case for renumbering benefits from IPv6 deployment. Thanks for listening! Sponsor: ITProTV This episode of IPv6 Buzz is brought to you by ITPro.TV.
