Configure DNS server

For each created Wide area mobile print sub domain, the DNS requests for those sub domains, should be delegated to SAFEQ Cloud, so SAFEQ Cloud can respond with relevant printer details for the sub domains.
For more information about Zone Delegation, refer to the following articles:

Wikipedia: DNS zone

Microsoft: Create a zone delegation

For example configurations of the zone delegation, refer to below two sections on Microsoft Windows DNS BIND (Mac OSX or Linux).
