I'm consolidating my personal projects in one place. As such the old GitHub repo is being archived, and work now continues on sourcehut.
Prints your public IP address to stdout by querying a specified STUN server.
Useful for finding your public IP when behind a NAT or firewall. Uses an open standard that's faster and arguably safer than querying some rando's "what is my ip" website.
$ cargo install iplookup
$ iplookup stun.l.google.com:19302
123.456.789.123
$ git clone git@github.com:nickbp/iplookup
$ cd iplookup
$ cargo build --release
$ ./target/release/iplookup stun.l.google.com:19302
123.456.789.123
Note: Building iplookup requires Rust 1.39.0 or later.
- To simplify scripting, the only thing written to stdout is the resulting public IP. Anything else goes to stderr.
- Automatic retries with exponential backoff, waiting a maximum of 31s for a response.
- Prints additional information about the request and response if the
DEBUGenvironment variable is non-empty.
