IP Calc is a must-have iPhone app for network engineers, enabling one-tap IPv4/IPv6 address calculations. It accelerates and refines your design and operational workflows.

Home Screen & Favorites Management

History List: View recent calculation results with timestamps

Favorites: Star frequently used results and recall them from the top screen with one tap

One-Click Delete/Clear: Remove individual entries or wipe all history at once

IPv4 Address Calculation

Direct Input & CIDR Slider: Enter IP address/subnet mask or adjust prefix (/0–/32) via slider

Results: Network address, broadcast address, wildcard mask, first/last host, total/usable hosts, global/private classification

Binary View: Inspect bit-level details and copy-paste directly into documentation

History Save: Add current settings to history with one tap to skip manual re-entry

IPv4 Subnet Wizard

Parent Network: e.g., 218.100.9.248/29

Subnet Division: Select /30–/32 and see subnet count update automatically

Subnet List: Card-style list showing network address, CIDR, host count, and address range

Clipboard Copy & Details: Copy any subnet info with one tap and jump to its detailed view

IPv6 Address Calculation

Full ⇔ Compressed: Toggle between full and compressed notation with one tap

Prefix Slider: Intuitive control for /0–/128 prefixes

EUI-64 Generation: Input a MAC address to instantly generate a flipped-bit, FFFE-inserted interface ID

Results: Network prefix, interface ID, type (global unicast/unique local, etc.), total address count, binary view

IPv6 Subnet Wizard

Flexible Splitting: Divide a /64 parent network into any length (e.g., /68–/96)

Bulk Generation: Create up to 65,536 subnets at once, browse as cards, copy or view details

Enterprise-Grade: Perfect for large-scale sites and data-center network design

With IP Calc, instantly visualize complex IP address and subnet designs, boosting both efficiency and accuracy in your network engineering tasks. Try it today!
