NICs with custom DNS settings#
Operational Excellence · Network Interface · Rule · 2020_06 · Awareness
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.
