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 • Binary representation of the address and mask 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 — Copy any value with a long press — 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. [Languages] Japanese and English. [Privacy] Calculations stay on your device.
