// SECURITY TOOLKIT
Defensive analyst tools, built in.
Nine practical tools for hardening and triage — all running natively on the platform. Network tools are rate-limited and refuse internal targets.
CIDR / Subnet Calculator
Defensive utilities only. Network tools refuse internal/reserved addresses and are rate-limited.
Frequently asked questions
What does a /24 give me?
A /24 is 256 addresses (254 usable hosts) — one common LAN-sized subnet.
Does this work for IPv6?
Use it for IPv4 subnetting; IPv6 prefix planning follows the same CIDR logic with far larger ranges.
