Secondary Solution

NOTE: This option is only intended for experienced users of DNS. This option requires that you already have a name server and you are looking for DNS redundancy.

Even if you already have your own name server it is always better to have additional servers for robustness. You will probably want to set up more than the required two name servers for you domains. DNS Made Easy has a solution to offer you a highly flexible slave name server.

Why is DNS Made Easy your best choice for a secondary name server option?

• DNS Made Easy allows you to create a secondary name server in seconds.
• You can configure your secondary server to use TSIG (transaction signatures). TSIG uses shared secrets and a one-way hash function to authenticate DNS messages. This make your DNS transfers very secure! You provide the hash and we will tell you what to name the key.
• You can easily assign the IP of the master name server.

What extra steps would I need to take when using TSIG with my Secondary DNS?

One problem with TSIG is that it requires time synchronization. The timestamp in the TSIG record is useful for preventing replay attacks, but it may cause problems if the clocks on the name servers are not synchronized. To solve this problem DNS Made Easy servers all use NTP. http://www.eecis.udel.edu/~ntp/

What does it take to have DNS Made Easy be your Secondary DNS?

Tell the Registrar with which you registered (or which you will register) that your domain will be using DNS Made Easy's secondary nameserver(s). You will have to provide some (or all) of the following information:

• Nameservers:
  • ns5.dnsmadeeasy.com - 63.219.151.12
  • ns6.dnsmadeeasy.com - 64.246.42.203
  • ns7.dnsmadeeasy.com - 205.234.170.139

   

• If you limit your nameservers to only allow transfers to certain IPs then the nameservers that you will want to allow transfers from are:
  • 63.219.151.12
  • 64.246.42.203
  • 205.234.170.139
