Secondary DNS

Secondary DNS

The use of a secondary DNS in another network other than the primary DNS will enable your visitors to have access to your website just in case of a master DNS breakdown. This is a free service for all dedicated servers.

You can save your domains on the secondary DNS server of OVH.com for all zones that you manage on your server:

  • For OVH.com servers: sdns1.ovh.ca
