IPB143: Are We Stuck With Dual-Stack Forever?

IPB143: Are We Stuck With Dual-Stack Forever?

These days, most network devices can speak both IPv4 and IPv6. A dual-stack approach can smooth the transition from one protocol to the other because organizations can get comfortable with IPv6 without having to make a hard cutover. However, they may get so comfortable that they never fully commit. In this episode Ed, Scott, and... Read more »

IPB138: Making Sense Of DHCPv6 Prefix Delegation (DHCPv6-PD)

IPB138: Making Sense Of DHCPv6 Prefix Delegation (DHCPv6-PD)

DHCPv6 Prefix Delegation (DHCPv6-PD) is an IETF RFC that lets one router delegate a long-lived prefix, using DHCP, to a requesting router. What’s the need for this? As the RFC notes, some applications expect stable addresses. It also notes: It is appropriate for situations in which the delegating router does not have knowledge about the... Read more »
