SprintLink DNS FAQ
What is DNS?
A. DNS stands for Domain Name Service. DNS is an Internet Standard for resolving the names of individual machines into IP addresses and vice versa. This resolution is perfomed by machines called nameservers, and these nameservers turn things like the names of web and mail servers into IP addresses.
Do I need DNS?
A. The Internet functions using IP addresses, not names, so a nameserver is necessary if you are going to use a website or mail server. Not everyone needs DNS. If the machine in question is not supposed to be found on the internet, a good way to hide it is to NOT provide DNS for it. It doesn't stop people from connecting to the IP address, but it does make it harder to find the machine.
Is DNS the same thing as a Domain or a Domain Name like "my-company.com" ?
A. Not quite. DNS is a service, not an object. DNS is the process of turning the name you register into an IP address so that humans can remember the name, and the computers, which use numbers, can translate the name the humans understand into the numbers they understand.
Does Sprint offer DNSSEC?
A. Yes, Sprint offers DNSSEC. Please contact your account representative to purchase this service.
Does Sprint offer TSIG security for zone transfers?
A. Yes. Simply submit your TSIG request in the comments section of your secondary zone transfer on the DNS change form within Compass.
Does Sprint register Domain Names?
A. Sprint does not provide domain name registration services. Please see ICANN's website for a list of accredited domain name registrars. Sprint makes no specific recommendations to use any specific registrar.
Can Sprint do my DNS for me? If so, how do I set this up?
A. YES, and for free, but only if:
  1. you are a dedicated Internet customer of Sprint
  2. you are NOT a reseller of Internet services
  3. only for a limited number of domains (see the DNS Policy page for more information)
  4. Sprint can provide Primary and Secondary Authoritative DNS in both Forward and Reverse for most customers.
What are the names and IP addresses of Sprint's Nameservers?
A. Sprint maintains two sets of DNS servers. The first functions as Authoritative (non-recursive), and the second functions as Cache-Only (recursive).
The authoritative servers provide Primary or Secondary Authoritative DNS for customers. If you are having Sprint perform Internet accessible DNS for your domain name, then you will need to provide your registrar with Sprint's nameserver names and IP addresses. The Authoritative machines will NOT resolve any domain that they are not Authoritative for. Using the IP's and names of the Sprint Authoritative servers will not work on client machines trying to resolve random Internet addresses. The Cache-only servers should be used for local client resolution. Here is the list of the authoritative servers.

The Cache Only servers can be used by customer host machines to perform general DNS. You can put the IP addresses in the client machines on your network if you do not have your own Internet nameserver. These servers are replicated around the world and your connection will be taken to the closest server.
