Tools in your terminal
Use DNS lookup, SSL check, port check and your IP address with a single curl command in your terminal, without a browser. Handy in scripts and on servers.
Use our tools with curl
You do not need to open a browser. A command in your terminal returns the answer as plain text, handy in scripts and on servers without a screen.
curl https://geekstation.nl/ip
Your public IP address, nothing else.
curl https://geekstation.nl/dns/geekstation.nl
curl https://geekstation.nl/dns/geekstation.nl/MX
DNS records for a domain, or just one type (A, AAAA, MX, NS, TXT, SOA, CAA).
curl https://geekstation.nl/ssl/geekstation.nl
The SSL certificate: who issued it, how long it is valid and which encryption is used.
curl https://geekstation.nl/poort/22,80,443
Tests whether these ports are open on your own IP address. This only works for the address you connect from.
curl https://geekstation.nl/hulp
An overview of all commands (the help text is in Dutch).
Add ?json to a command to get the answer as JSON, for example curl "https://geekstation.nl/dns/geekstation.nl?json". Put the address in quotes, otherwise your terminal treats the question mark as a special character.
There is a per-minute limit so the service stays fast for everyone. What you look up stays in the server log for 7 days; we store nothing else. Would you rather click than type? Use the regular tools: DNS lookup, SSL certificate check, Port checker and What is my IP?.
