    Understanding Carrier-Grade NAT (CGN) And IPv6

    Understanding Carrier-Grade NAT (CGN) And IPv6

    In this week’s episode, Ed and Tom talk discuss the impact that service provider deployment of Carrier Grade NAT (CGN) has had on the overall adoption of IPv6.

    Our guests are Kevin Myers and Nick Russo. Kevin and Nick have both worked with CGN and IPv6, and Nick is designing an IPv6 training course on Pluralsight.

    Topics discussed include:



    * What is CGN and how is it deployed in service provider networks today? How has CGN deployment changed over time?

    * Is CGN a technology that should be included in IPv6 training?

    * What have historically been CGN’s biggest liabilities? What issues still exist for it?

    * Should CGN and IPv6 coexist?

    The Ghosts Of IPv6

    The Ghosts Of IPv6

    Ed, Scott, and Tom talk about some deprecated and retired IPv6 technologies, as well as  why some of this stuff just didn’t get adopted. IPv6 has had a long time to mature. Along the way, many creative ideas were brought forth by the IETF (as RFCs) and vendors (as product features).

    But after deployment experience grew, these erstwhile standards and features didn’t make the cut. Join us as we “pour one out” for these technologies that didn’t make it.

    Topics discussed include:



    * ISATAP and Teredo tunneling

    * DNS A6 records

    * Site-local addressing (fec0::/10)

    * IPv4-Compatible IPv6 Addresses

    Revisiting IPv6-Only

    Revisiting IPv6-Only

    In this week’s episode Ed, Scott, and Tom revisit the topic of IPv6-only and discuss its current state in service provider networks, in the data center, and even to the desktop.

    Topics discussed include:



    * How hosts behave on IPv6-only networks

    * What auto-addressing (SLAAC and DHCPv6) tweaks will we likely see to optimize IPv6-only networks

    * Where enterprises might consider an IPv6-only deployment

    * Key technologies enterprises need to be aware of when considering IPv6-only

    Reviewing DNS Flag Day 2020

    Reviewing DNS Flag Day 2020

    DNS Flag Day is a community effort by service providers and DNS software vendors to address DNS issues and ensure that this critical protocol functions efficiently and effectively.

    In this week’s IPv6 Buzz episode, Ed and Scott speak with guest Andrew Wertkin about the DNS flag day for 2020, which took place October 1st. They discuss the issues that the Flag Day covered, as well as IPv6. Andrew is the Chief Strategy Officer at DDI vendor BlueCat Networks. Prior to that he was CTO at software company PTC.

    Topics discussed include:



    * What is DNS Flag Day and how did it come about?

    * The DNS community’s motivations for this effort and what it’s trying to achieve

    * DNS behavior that listeners should look for that might indicate they aren’t current with their DNS settings and configuration

    * The differences between IPv4 and IPv6 DNS

    Weird And Wacky IPv6 Addressing

    Weird And Wacky IPv6 Addressing

    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

    Why the Internet Needs IPv6 - With Special Guest Vint Cerf

    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
