Things I got tired of searching for

Tools

These are small utilities I wanted close at hand, so I put them on my own site. Some are for work, some are for driving, and some exist because opening a search result full of ads just to calculate a subnet felt unnecessary.

01

Domain Inspector

One place to check registration details, DNS, nameservers, TLS certificates, redirects, and domain-renewal limits when I am trying to figure out what a domain is actually doing.

Inspect a domain
02

IP Subnet Calculator

Network ranges, masks, usable hosts, broadcasts, and CIDR details without needing to remember whether I am doing the binary math correctly before coffee.

Calculate a subnet
03

Cisco Configuration Generator

A starting IOS configuration for common device, interface, routing, and access settings. I still want to understand the configuration, I just do not enjoy typing the boilerplate twice.

Generate a configuration
04

Developer Tools

JSON formatting, URL and Base64 encoding, UUID generation, and Unix timestamp conversion. The little jobs that interrupt a larger job.

Open developer tools
05

Password Generator

A straightforward random password generator with configurable length and character options.

Generate a password
06

Bus Driver HOS Calculator

A very different kind of calculator: driving, on-duty, and break time for passenger-carrying drivers. This is what happens when your personal site covers both servers and buses.

A note about privacy: Browser-only utilities keep their input in the browser where noted. Tools that inspect domains obviously have to contact outside services to retrieve current DNS, registration, certificate, or HTTP data.
