NetBits vs IT電卓+

NetBits is a fast, no-nonsense IP subnet calculator. Enter an IPv4 address and subnet mask — or just type CIDR notation like 192.168.1.10/24 — and instantly get: • Network and broadcast address • Wildcard mask • Usable host range (min / max) • Number of usable hosts • Network class (A–E) and address type: Private, Public, Loopback, Multicast, CGNAT and more • Binary representation of the address and mask Need to plan a network? Split it into subnets: • Equal parts — pick a subnet mask and see every subnet with its host range and broadcast address • By hosts (VLSM) — enter how many hosts each network needs, and NetBits gives each the smallest subnet that fits and shows the free space left Built for network engineers, sysadmins, students, and anyone who needs quick, accurate subnet math without ads or clutter. FEATURES — CIDR notation input — Binary address/mask view — Subnet splitting: equal parts or VLSM — Copy any value with a long press — Share the result or the list of subnets as text — Light and Dark mode — English and Russian PRIVACY NetBits works fully offline. No accounts, no analytics, no data collection — ever.

IT電卓+ is a focused calculator for engineers, network administrators, and learners studying for IT certifications. Four common tasks are organized into simple, switchable tabs. [Unit Conversion] Convert between bit, B, KB, MB, GB, TB, and PB. Toggle between SI prefixes (base 1000) and IEC prefixes (base 1024 — KiB, MiB, etc.) so you can match the convention you need for storage, memory, or traffic. [Subnet Mask Calculator] Enter an IPv4 address and a CIDR value to get the network address, broadcast address, first and last usable host, subnet mask, wildcard mask, and host counts. /31 (RFC 3021) and /32 are handled correctly as special cases. [Base Conversion and Bit Operations] Convert between binary, octal, decimal, and hexadecimal. Binary output is grouped every four bits for readability. AND, OR, XOR, left shift, and right shift are available on the same screen. [Link Speed and Transfer Time] Convert across bps, Kbps, Mbps, Gbps, B/s, KB/s, MB/s, and GB/s. Combine a file size with a link rate to estimate how long a transfer will take. [16 languages] Available in 16 languages: Japanese, English, Simplified and Traditional Chinese, Spanish, Portuguese (Brazil), Korean, German, French, Hindi, Indonesian, Russian, Italian, Turkish, Thai, and Vietnamese. The app follows your device language. [Privacy] Calculations stay on your device. The app does not upload your inputs or results. [Price and ads] The app is free, with every feature available from the start. There are no in-app purchases or subscriptions. A banner ad is shown at the bottom of each screen. You choose whether ads may be personalized on first launch and can change it at any time under "Ad settings" in Settings.
