CIDR Subnet Calculator — Plan and Design IP Networks Efficiently

Network engineers and DevOps administrators frequently need to divide networks into subnets. Toolich's CIDR Subnet Calculator computes subnets, IP ranges, broadcast addresses, and wildcard masks instantly.

Enter any base IP address and choose a CIDR mask to see a breakdown of the network block size, usable hosts range, binary equivalents, and binary subnet masks.

Designed to simplify VPC configuration on AWS, Google Cloud, or Azure, helping you allocate clean, non-overlapping IP blocks.
