Dear Qwest Customer,
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".
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.)

...you must make changes immediately to reflect the correct IP addresses:
Primary: 205.171.3.65
Secondary: 205.171.2.65
Change Description
** Add RESOLVER2.QWEST.NET (or IP address: 205.171.2.65) as the secondary DNS server.
*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.
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).
