ipcheck diagnoses the real network paths used by Codex and Claude Code, including configured proxy and gateway routes.
Install it in one command:
brew install jacklv-coder/tap/ipcheckOr tap first if you prefer the short formula name:
brew tap jacklv-coder/tap
brew trust --formula jacklv-coder/tap/ipcheck
brew install ipcheckHomebrew 6 requires explicit trust for non-official taps. The one-command
fully qualified install trusts only the ipcheck formula automatically; it
does not trust every formula in the tap.
Upgrade later with:
brew update
brew upgrade ipcheck
