DNS Zones
Overview
Section titled “Overview”The solution uses three DNS Zones.
maxconf.ca,vc.maxconf.ca, andtest.vc.maxconf.ca
These zones are public. They are used to provide access to various Azure services via the above domains.
Name Server Cascade
Section titled “Name Server Cascade”maxconf.ca is hosted on Webnames. NS records have been modified in Webnames to allow Azure ownership of DNS resolution on this domain.
The Azure DNS zone maxconf.ca has NS records with a value of vc pointing at the name servers for Azure DNS zone vc.maxconf.ca
The Azure DNS zone vc.maxconf.ca has NS records with a value of test pointing at the name servers for Azure DNS zone test.vc.maxconf.ca
API Records
Section titled “API Records”The Azure DNS zone vc.maxconf.ca has a CNAME record with a value of api pointing at the Production API Layer apim-maxconf-prod.azure-api.net
The Azure DNS zone test.vc.maxconf.ca has a CNAME record with a value of api pointing at the Production API Layer apim-maxconf-test.azure-api.net
Pexip Node Records
