NICs with custom DNS settings#

Operational Excellence · Virtual Machine · Azure.VM.UniqueDns

Network interfaces (NICs) should inherit DNS from virtual networks.

Description#

By default Virtual machine (VM) NICs automatically use a DNS configuration inherited from the virtual network they connect to. Optionally, DNS servers can be overridden on a per NIC basis with a custom configuration.

Using network interfaces with individual DNS server settings may increase management overhead and complexity.

Recommendation#

Consider updating NIC DNS server settings to inherit from virtual network.
