A small, growing collection of browser-based utilities I’ve built for the kind of networking and identity work I write about on this blog. No signup, no account, and no tracking beyond what’s needed to run the tool.
IP Tools →
Convert between an IPv6 unique local address (ULA) and an embedded IPv4, run CIDR/subnet math, and look up IP geolocation — all in one page.
More tools will land here over time. Have an idea for one, or found a bug in an existing one? Let me know.
