Pointing DNS to NetDocuments Over MPLS Circuit

Set up a DNS conditional forwarder and point it to the DNS server according to the region of the circuit end-point.

  •  US DNS Server: 192.100.0.215
  •  UK DNS Server: 185.83.176.166
  •  AU DNS Server: 103.225.142.226

 Set up the conditional forwarder to forward the following zones:

  • *.netvoyage.com
  • *.netdocuments.com

Instructions on setting up the forwarder can be found online. 
This is a link to the PowerShell command documentation but it can also be achieved from the DNS snap-in from your DNS server. 

Route the entire IP block below through your MPLS circuit based on the region of your circuit end-point:

  •  US - 192.100.0.0/24
  •  UK - 185.83.176.0/24
  •  AU - 103.225.142.192/26

 **NDmail customers will need to exclude the following IP address from routing over the MPLS circuit according to region:
US - 192.100.0.196/32
UK - 185.83.176.148/32
AU - 103.225.142.196/32
This will allow a response back to NDmail when it communicates with your exchange server over the internet.

 

Important:  In the event of an MPLS circuit outage, the Conditional Forwarder should be removed.  This will force DNS queries to resolve to our Akamai IPs and allow the NetDocuments service to remain accessible for local users.  After circuit recovery, the Conditional Forwarder can be re-added to the local DNS server.
