DNS Resolver IPs
Posted by - NA -, Last modified by Kevin Stange on 24 April 2013 06:58 PM

DNS resolvers are used to look up IP addresses, mail servers, and other information related to a domain name.  Resolvers are required to use the Internet effectively.  This article describes the resolver configuration for servers hosted with Steadfast.  A new dedicated server or cloud VM will automatically be configured to use these settings by default.

We provide the following DNS resolver addresses for all customers on our network:

IPv4:

  • 216.86.146.8
  • 216.86.146.9

IPv6:

  • 2607:f128:1::2
  • 2607:f128:1::3

If your server connects only to our Internal Network and has no public Internet Connection:

  • 10.1.251.10

You can enter the appropriate IP addresses under "Resolver IPs" in your Windows Interface Configuration, in WHM, or by inserting the following lines into /etc/resolv.conf on a Linux or FreeBSD system:

nameserver 216.86.146.8
nameserver 216.86.146.9

The pairs of IPs above are each hosted on physically separate servers.  You should always use at least two separate servers, if possible.  Feel free to use these IPs as backup addresses even if you run your own DNS resolver.

Please note that if you are considering running your own resolver, you should make sure it is not publicly available unless absolutely necessary.  Please see our article about DNS Amplification Attacks for further information.
