VNet & Subnet Address Planner
Design your Azure network before touching the portal. Add subnets, check for conflicts and see exactly how many IPs you'll actually be able to use.
VNet Address Space
💡 Common ranges: 10.0.0.0/16 (65,536 IPs) · 10.0.0.0/24 (256 IPs) · 192.168.0.0/16
Subnet Manager
⚠️ Azure automatically reserves 5 IPs per subnet for internal use (gateway, DNS, broadcast). A /24 subnet gives you 256 − 5 = 251 usable IPs.
