v6ops

Summary

The v6ops meeting covered several important topics related to IPv6 deployment and operation. Presentations included updates on IPv6 education initiatives, frameworks for IPv6 as a service, operational issues with hop-by-hop options, prefix delegation in home networks, CDN behavior with IPv6 extension headers, using DHCPv6 prefix delegation, IPv6 multi-homing, and IPv6-only resolvers in NAT64 environments. Discussions were lively, reflecting the ongoing challenges and potential solutions for broader IPv6 adoption.

Key Discussion Points

IPv6 Textbook for College Students: Progress is being made, with contributions and commits steadily increasing.
IPv6 for Enterprise: Work is ongoing to address IPv6 deployment challenges in enterprise networks.
Framework for Multi-IP Network & IPv4 as a Service: The draft has been updated based on feedback and is progressing. The use of IPv6-only headers was proposed for brevity.
Operational Issues with Hop-by-Hop Options: The draft is considered mature and ready for working group last call.
IPv6 Prefix Delegation in Home Networks: Discussion focused on hierarchical vs. flat delegation models and the implications for router configuration. The benefits of standardising on the approach were discussed.
CDN Behavior with IPv6 Extension Headers: Testing revealed inconsistencies in CDN handling of extension headers, but improvements were observed. Discussion around proxy implementations in CDNs impacting EH functionality was discussed.
Using DHCPv6 Prefix Delegation: Proposal to use DHCPv6-PD instead of address assignment for IPv6 to scale the network resources. Concerns were raised about tracking user behaviour with it.
IPv6 Multi-homing: An informational draft outlining the challenges and options for IPv6 multi-homing was presented. There are operational challenges involved.
IPv6-Only Resolver in NAT64: Proposal to have IPv6 only the way to resolve. It addresses the case where some people are using Diana six four not sixty four.
IPv6 stack migration: Dual stack migration for in-house private cloud.

Decisions and Action Items

Hop-by-Hop Options Draft: The draft is targeted for working group last call.
Multi-homing Draft: Additional text on the issues with using one address space on another provider will be added.
Prefix Delegation Draft: Add examples for host. The text related to Host and separate Pd were to be updated. The document will need some new text.

Next Steps

Continue discussion on the IPv6 prefix delegation draft on the mailing list.
