Subnet Visualizer
See any CIDR as binary maps — IP, mask, and network bits plus a 32-block network/host bar. Single-network rendering only, no sub-subnetting — local rendering, free, no signup.
How to Use the Subnet Visualizer
Similar Tools You Might Need
See allSubnet Calculator
Compute subnet masks, network/broadcast addresses, and usable host ranges from any CIDR. Plan a /24 office network correctly — local math, free, no signup.
CIDR Calculator
Convert CIDR prefixes to masks, ranges, and host counts — /8 through /32 decoded. Answer 'how many IPs in a /22' instantly — local math, free, no signup.
SSL/TLS Checker
Check a host over HTTPS from your browser — SSL/TLS reachability (which proves the browser validated the certificate chain) plus public issuance history (issuer, expiry, cert count) via crt.sh. No cipher-suite or protocol-version scan: browsers do not expose handshakes.
Bulk AVIF Optimizer
Convert and compress images to AVIF via canvas encoding with 4 presets — Web 1920px/q60, Balanced 2048px/q75 (default), High Quality 3000px/q85, Maximum original-size/q95 — plus free quality (10–100) and max-width (0–4000, 0 = Original) sliders that decouple the preset. Only wider images downscale; single saves as optimized.avif, batches as *.avif in avif-images.zip — local work, 2 free batches a day.
Grade Calculator
Convert a single course percentage into its letter grade on the built-in plus/minus scale — see that an 85 earns a B instantly. Free, local, no signup.
Frequently Asked Questions
How do I split a /16?
The tool does not subdivide networks — it renders one CIDR as binary rows and a network/host bar. Plan department splits separately.
What do the colors mean?
Green blocks are network bits, muted blocks are host bits — a single two-tone bar, not per-subnet bands. No overlap detection.
Can I export the plan?
Copy gives the IP/mask/bit-count readout as text — there is no allocation table or map image.
Is my plan uploaded?
No — visualization renders locally in your browser. Nothing leaves your device.
