DNS is the name service for Internet addresses that translates friendly domain names to numeric Internet Protocol (IP) addresses. For example, "www.tamu.edu" translates to 165.91.22.88. This is accomplished by a collection of computers scattered across the Internet that are running DNS "nameserver" software. These computers cooperatively make it possible for different organizations on the Internet to exchange IP name resolution information.
For DNS to work, your computer needs to know the IP addresses of the local DNS servers. For many computers, this information is automatically provided. For some computers, the DNS servers IP addresses will need to be manually configured.
For computers on the Texas A&M University networks that need to be manually configured, the IP addresses for the nameservers are:
Search Order Server Address First dns-cache-1.net.tamu.edu 128.194.254.1 Second dns-cache-2.net.tamu.edu 128.194.254.2 Third dns-cache-3.net.tamu.edu 128.194.254.3 The ordering of the DNS servers is important and you should list the DNS servers in the same order as they are listed above. All three DNS servers should be listed.
For systems on the TTVN networks that do not have a local DNS server, the following DNS servers and order is recommended:
Search Order Server Address First dns.ttvn.tamus.edu 165.95.0.178 Second dns-cache-2.net.tamu.edu 128.194.254.2 Third dns-cache-3.net.tamu.edu 128.194.254.3 To help minimize response time for DNS queries and reduce traffic on our Internet link, the CIS Network Group maintains a locally mirrored DNS-based Blackhole List.
