Azure DNS has three operational asymmetries that affect multi-VNet and hybrid architectures: reverse DNS (PTR) lookups are scoped per-VNet so queries for IPs in peered VNets return NXDOMAIN, DHCP leases must be manually renewed on all affected VMs after changing VNet DNS server settings, and cross-VNet name resolution requires FQDNs because hostname-only resolution is insufficient across VNet boundaries.
