Yes. Azure reserves the first four and last IP address for a total of 5 IP addresses within each subnet.
For example, the IP address range of 192.168.1.0/24 has the following reserved addresses:
• 192.168.1.0 : Network address
• 192.168.1.1 : Reserved by Azure for the default gateway
• 192.168.1.2, 192.168.1.3 : Reserved by Azure to map the Azure DNS IPs to the VNet space
