It is time to begin the process of transitioning IETF IT services from Neustar Secretariat Services (NSS) to Association Management Solutions (AMS). The complete process will take place over approximately 7 weeks, beginning Friday, 14 December 2007, and continuing through Thursday, 31 January 2008. The first step in the process is to move DNS services. The actual transition will take place on Friday, 14 December 2007, at 12pm Eastern (1700 UTC), approximately 44 hours from now. At that time the NS records for the following domains: iab.org iesg.org ietf.org irtf.org Will all be changed to the following: NS4.AMSL.COM 64.170.98.30 NS5.AMSL.COM 64.170.98.31 NS6.AMSL.COM 2001:5c0:9758::1:1 Please note that IPv6 DNS services will initially be provided by an IPv6 tunnel. AMS is adding an additional OC-1 fiberoptic circuit to serve the IETF, which will include native IPv6 services. When that installation completes, which is expected in January 2008, all IPv6 services will be available natively from AMS. While we wait for AMS' dedicated circuit, only DNS services will be made available through this IPv6 tunnel. This may affect email and mailing list services, which are expected to transition in early January 2008. If the circuit installation is not complete before we transition email and mailing lists then those services may temporarily be unavailable on IPv6. We will keep you informed. We understand that this is an inconvenience for part of the user community but, unfortunately, it is unavoidable. AMS will make native IPv6 available as soon as they can. Note that the DNS will continue to return IPv6 addresses when queried for those services that have not yet transitioned (for example, the web and ftp which transition last). On the upside, all IT services will have IPv6 addresses when the transition is complete. Until then, those services that currently have IPv6 addresses will lose them as they transition. Finally, some of you will notice that those two IPv4 nameservers are both on the same subnet. This is a transitional situation. AMS is building a mirrored architecture in their primary facility. When the transition from NSS completes on 31 January 2008, they will begin the process of moving the mirrors to their secondary facility in Orlando, FL. This transition is expected to be transparent to the community and will take place over approximately 30 days. There will be more to say about this when that transition begins.
