IMPORTANT: Qwest Change of DNS Service Notification

Dear Qwest Customer,

If you currently still have ANY of the following legacy name server IP addresses or hostnames in your "TCP/IP, DNS," or other types of hostname resolver settings...

204.147.80.5, ns1.uswest.net
206.196.128.1, ns2.uswest.net, ns2.dnvr.uswest.net
204.147.80.1, ns3.uswest.net, ns3.mn.uswest.net
216.111.65.217, ns1.qwest.net
205.171.16.250, ns2.qwest.net

...you must make changes immediately to reflect the correct IP addresses:

Primary: 205.171.3.65
Secondary: 205.171.2.65

Note:The following information was published previously, but is being republished for your convenience:

Please be advised that in order to continue to provide the best possible DNS service, Qwest will be updating the addresses of the qwest.net DNS servers on October 21, 2004. Qwest has implemented a dedicated, high-availability DNS service for the purpose of providing recursive DNS name resolution services. This service performs DNS lookups on the behalf of client hosts and workstations. It is this service that enables Internet applications to locate resources by name, such as establishing a network connection with a host-name found in a typical Web URL. For example, given the URL http://www.example.org/home.html, recursive DNS name resolution allows a web browser to obtain the IP address of the host named "www.example.org", and thereby establish an HTTP session in order to retrieve the web page "home.html".

Change Description

Qwest customers will be required to change their DNS service configurations in order to begin using the new service. This service is highly redundant with automatic real-time fail-over capabilities implemented among seventy-five servers distributed throughout the core Qwest network. The service insulates the customer from changes in the system, allowing maintenance and upgrade activities to be performed without service interruption.

In order to eliminate performance, maintenance, and security conflicts with authoritative DNS services, pre-existing recursive DNS services provided by multipurpose legacy servers will be terminated. This means that if you are currently using either ns1.qwest.net (or IP address: 216.111.65.217) or ns2.qwest.net (or IP address: 205.171.16.250) for your DNS configuration, you must change your settings to use the new service addresses, * RESOLVER1.QWEST.NET (or IP address: 205.171.3.65) and ** RESOLVER2.QWEST.NET (or IP address: 205.171.2.65). (Please refer to "Customer Client Settings" instructions below.)

* Please note: If you currently have the hostname, "RESOLVER.QWEST.NET" in your DNS settings, it is not neccessary to change the hostname to "RESOLVER1.QWEST.NET," Either name, "RESOLVER.QWEST.NET" or "RESOLVER1.QWEST.NET" may be used, since each has the same IP address - 205.171.3.65.
** Add RESOLVER2.QWEST.NET (or IP address: 205.171.2.65) as the secondary DNS server.

The legacy service (on ns1.qwest.net and ns2.qwest.net) will be partially shutdown on June 21, 2004. Following this date, you may experience degraded service. The service will be completely terminated four weeks later on October 21, 2004. Following this second date, name resolution services will no longer be available from either ns1.qwest.net or ns2.qwest.net. * Therefore, you must make all necessary changes before October 21, 2004 to avoid interruption in your DNS service.

*The new service is currently available for your use so you can make the appropriate changes now. Please make the necessary changes as soon as possible to avoid any interruption in your DNS service.

Note that this change only impacts recursive name resolution services, which are used by client applications to perform general lookups of domain names on the Internet. This change does not affect authoritative services by which domain names are made public on the Internet. In other words, do not change your domain's name servers listed with your domain registrar (such as Network Solutions). In addition, this change does not impact zone transfer or notification settings of customer managed DNS systems.

UNIX (Linux, Solaris, FreeBSD, etc.)

The file /etc/resolv.conf must be updated to specify the following two nameserver entries. These shou ld be the first two lines in the file. 

nameserver 205.171.3.65
nameserver 205.171.2.65

Any entries that refer to other Qwest DNS server addresses must be removed.

If the network settings are obtained via DHCP or PPP, such as for a Qwest DSL or Dial-up connection, this fi le should already contain these entries, no changes are required.

This should work for Mac OS X as well (for those who are comfortable using the Terminal utility t o access the UNIX command line).
