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.)
