SubnetPro: IP Calculator
IP Subnet Calculator
$1.99 · Designed for iPad. Not verified for macOS.
Instant subnet math: ranges, splits, binary view, CIDR converter. Built for network pros.
SubnetPro is the subnet calculator network folks actually want: fast, complete, and beautiful. IPv4 and basic IPv6, with every field one tap from your clipboard.
EVERYTHING FROM ONE INPUT
Type an IP with a CIDR prefix or a mask, and SubnetPro instantly shows the network address, broadcast, usable host range, host count, wildcard mask, and address class.
SPLIT NETWORKS IN SECONDS
Need to carve a /24 into eight subnets? The subnet splitter divides any network into N equal blocks and lists every resulting subnet with its range.
SEE THE BITS
A binary view breaks each octet down bit by bit, so the math is never a mystery — great for students chasing certs and pros sanity-checking a design.
BUILT FOR REAL WORK
CIDR-to-mask converter, copy on any field, and a history of recent calculations so you can jump back to that network from earlier.
Works completely offline — no account, no ads, no tracking. Built by a CCNP for people who do this all day. Pay once.
