All,
As you’re all aware, on 06/06/06 NSS successfully launched IPv6 services for
IETF Web, Mail, and FTP. Following the introduction, NSS received a few
technical questions pertaining to IPv6 services. Below you will find technical
information as it pertains to configuration and troubleshooting. In addition,
NSS is in the process of providing statistics on IPv4 vs. IPv6 that will be
posted on the IETF website.
IETF IPv6 platform configuration
* The IPv6 access to and from IETF is tunneled from a local edge router
over IPv4 to a global Internet2 backbone.
* All services run native IPv6 in a dual stack configuration.
* Only HTTP, SMTP, FTP, and DNS traffic are permitted through an IPv6
Native firewall (pings, traceroutes etc. are dropped)
* All services and devices are monitored and logged.
* Interdomain IPv6 is dependant upon DNS caching (specifically the
amount of time the global DNS is permitted to remember which IP
addresses are assigned within any given domain. This is controlled
with TTL values set on the authoritative DNS servers)
* eMail service supports messaging between IPv4 and IPv6, and will
prefer IPv6 if available.
Note: All IPv6 addresses are temporary. New static addresses have been
requested and will be implemented in the next few weeks.
IETF IPv6 Platform Troubleshooting
• Verify your local DNS client receives the following DNS answers from
your
local DNS server:
ietf.org IN NS ns1.neustar.com.
ns1.neustar.com IN AAAA 2001:503:c779:1a::9c9a:108a
ietf.org IN MX 10 stiedprmail1.ietf.org.
stiedprmail1.ietf.org IN AAAA 2001:503:c779:1a::9c9a:1096
www.ietf.org IN AAAA 2001:503:c779:b::d1ad:35b4
ftp.ietf.org IN AAAA 2001:503:c779:1a::9c9a:1095
* Verify connectivity as follows:
telnet 2001:503:c779:b::d1ad:35b4 80
telnet 2001:503:c779:1a::9c9a:1096 25
ftp 2001:503:c779:1a::9c9a:1095
