Project Info

Project Name: IPv6 Connectivity for Infrastructure
Target Audience: IPv6-capable users
Expiration/Delivery Date (required): 12/31/2009

Description/Summary: Fedora Infrastructure services are not reachable via IPv6. This plan allows FI to serve both IPv4 and IPv6 users.

Project plan (Detailed):

1. Discover and use native IPv6 connectivity if offered in each of our data centers.
   1. Telia is reported to have it
   2. Options: 6to4 gateway server, or 6to4 on each public-facing (static IP) server.
2. Convert services one by one to serve IPv6 natively.
   1. Proxy Servers
   2. MirrorManager

Goals:

Specific resources needed

• publictest instance in PHX for the 6to4 gateway and/or a proxy server which itself uses 6to4.

IPv6 Capabilities by Data Center

• PHX - unknown
• PHX2 - hardware capable, but native routing not configured, and no plans to enable.
• telia - native IPv6 available, need address space delegations
• tummy - none available. Request filed with Kevin Fenzi.
• serverbeach - none available.
• ibiblio - native IPv6 available, dynamic addresses assigned on ibiblio1 and its guests already.
• BU - not available yet, but testing will begin Spring 2010 with plans for production use by Fall 2010.
• osuosl - planned by "end of summer". Check back in a few months.

Potential IPv6 services given DC capabilities

As ibiblio already has IPv6 connectivity, these are the servers and their apps that could be easily enabled.

• proxy4 (therefore web apps behind it)
  • mostly set up in ~mdomsch/puppet ipv6 branch
  • need another IPv6 address (not stateless autoconf) for proxy4-2, then fix manifests/servergroups/proxy.pp so the v4 and v6 addresses for all the proxy4-2 match.
  • also modules/httpd/files/00-namevirtualhost.conf
• torrent1
  • however, our current tracker, bittorrent-4.4.0-5.el5 does not support IPv6
  • opentracker does. This is not packaged in Fedora yet, but the license is beerware so could be.
• ns2 (DNS)
• publictest[1234]

TODO

• branch libowfat for EL-5, build it, and build opentracker
• add GLUE record to NS2 with Network Solutions (domain registrar) for each domain (as needed)
