Migration Considerations for IPv6: IPAM

Date: March 3, 2022
Time: 16:00 UTC - 17:00 UTC
Slides: Slides
Recording: Recording

This is part of our “Migration Considerations for IPv6” series of educational webinars.

IP address Management (IPAM) is a critical tool of modern enterprise networks. IPAM not being a set Standard means there is a lot to consider when choosing an IPAM strategy and tool. IPv6 can present challenges due to its sheer scale of available IP Addresses. We will walk through features that can make this a seamless process and how tools can dramatically improve our IPAM solution’s accuracy and depth of information. We will finish up with a dive into the role our IPAM solution plays in overall enterprise security.

Getting Started with IPv6 on the Mainframe: Part 2

Slides: Slides
Recording: Recording

Concerned about adding a new protocol to your IP stack? Is someone in your company demanding that you have that capability on your mainframe? Don’t know what needs to be done and how much effort is involved? And what does it all mean?
Rob has done the hard work for you and can tell you what it takes to enable your mainframe systems for IPv6. This presentation will give you the few steps you need to get you going, to get IPv6 active on your z/OS system.
Rob started programming mainframe computers in 1971, and learned an exceptional array of languages, tools and techniques, all without internet assistance. He did some dazzling database work in the `80s, and wrote over half of the first online registration system for the University of Toledo. In the ‘90s he did contracts with three oil companies, a software company and a credit bureau, involving VM, MVS, VSE, OS/2, several flavors of Unix, and an equal variety of networking protocols. He is now with Chemical Abstracts Service, a division of the American Chemical Society, supporting z/OS, z/VM and Linux, along with proprietary networking software. He has been involved with and a fan of IPv6 since early this century, performing the configuration and software upgrades required to support it on the mainframe. He happily notes that the mainframe was the first platform configured for it, with applications using IPv6 sockets exclusively. Rob is also co-author of RFC8250.

This session discusses the ways enterprises might want to think about migration to IPv6. Some vulnerabilities may be the same as IPv4 while other will be different. Vulnerabilities may be introduced by additional complexity, for example, transition mechanisms or dual-stacking.When many enterprises think about security, a number of areas are involved. These include:

  • Audits/Compliance​
  • Threat detection
  • Risk analysis
  • Root cause determination
  • Encryption
  • Privacy​
  • Confidentiality
  • ​Penetration testing

Enterprises rarely switch over from IPv4 to IPv6 in one step. Generally, companies will run dual-stack for a time, where both IPv4 and IPv6 are available on devices. This doesn’t solve most of the problems IPv6 was designed to solve, so we will discuss the benefits and drawbacks of:

  • Dual-stack
  • NAT44
  • Dual-stack Lite
  • NAT64/DNS64
  • 464xlat
  • MAP-T
  • MAP-E
  • IPv6-Only

To be successful in implementing and understanding IPv6 networks, you need to first understand the IPv6 address methodology which is, in many ways, a fundamental change from the IPv4 paradigm. In this introduction, you will become familiar with what is different as well as what is the same with IPv6.

  • Public and private addresses
  • IPv6 Prefixes
  • IPv6 Address Structure
  • IPv6 Interface ID
  • IPv6 Addressing and Address Allocation Methods (stateless, statefull)
  • Address types, unicast, multicast, anycast
  • Address categories: global, site local, link local
  • Unique Local Unicast addresses
  • Zero compression
  • Special addresses (loopback, unspecified, IPv4 mapped IPv6)
  • Broadcast address elimination 

This webinar will be followed by a hands-on lab to illustrate the concepts shown.  You do not need any equipment to participate.  We will send full instructions so that if you wish, you may do the same commands / exercises but this is entirely optional.

Introduction to IPv6 Security

Date: October 8, 2020
Time: 00:00 UTC - 00:00 UTC
Slides: Slides
Recording: Recording

How security will be handled in IPv6 is a question asked by many. Myths abound. In this session, we will start to look at:

• NAT is not a firewall (security by obscurity)
• Complexities introduced by multiple stacks
• Risks introduced by not considering IPv6
• Reconn attacks and defense
• Local network attacks and defense
• Unauthenticated NDP (similar to ARP)
• Cache table exhaustion and ping-pong attacks
• Rogue device attachments
• Mitigations
• Extension Headers
• ICMPv6

This is only a start. In the following year, we plan to do a more detailed investigation of this critical area. There will be follow-on webcasts. In the survey to enterprises, many people said that this was a topic they considered very important.

This webinar will be taught by Jon Worley (ARIN) and Nalini Elkins (INTC). This is a part of the Community Grant to INTC from ARIN.
Jon will start by helping you better understand IPv6 address planning, how to determine the right block size for your organization, and how to plan for growth. We will include some real-life examples and even an opportunity to try your hand at planning for your own organization! Nalini will go into even more detail and provide some rules for IPv6 address planning.In this session, we will:

  • Review the important prefixes needed for an IPv6 address plan,
  • Do a sample address plan together,
  • Discuss how a good address plan makes security and routing policy easier,
  • Consider numbering your LAN segment, SSID, or VLAN,
  • Consider numbering for sites, backbone, links, Consider how to remember your addresses for diagnostics and troubleshooting, and
  • Look at plans that other enterprises have done.

Jon Worley is the Senior Technology Architect with ARIN and has been a member of the Registration Services team since 2004. He has experience with all ARIN policies and procedures for requesting, managing, and transferring IP addresses and AS numbers, including technical services such as ARIN’s RESTful API. Jon has spoken about these topics as well as IPv4 depletion and IPv6 adoption at many ARIN events.

Dual Stack and Transition Mechanisms

 Enterprises rarely switch over from IPv4 to IPv6 in one step. Generally, companies will run dual-stack for a time, where both IPv4 and IPv6 are available on devices. This doesn’t solve most of the problems IPv6 was designed to solve, so we will discuss the benefits and drawbacks of:

  • Dual-stack
  • NAT44
  • Dual-stack Lite
  • NAT64/DNS64
  • 464xlat
  • MAP-T
  • MAP-E
  • IPv6-Only

DHCPv6Although IPv6 provides new addressing possibilities (SLAAC), most enterprises will want to continue using DHCP — which is now DHCPv6. We will describe how a client finds a DHCPv6 server, what information it can request and expect back. We will compare DHCPv6 to SLAAC.  We will discuss:

  • DHCPv6 Solicit Advertise, Request, Reply
  • DHCPv6 multicast addresses
  • IA_NA, IA_PD
  • Prefix “hints” to request the same prefix, or any prefix of a certain size
  • Additional information (DNS, transition mechanism, etc.)
