+ip라는 명령어가 사용되지 않는다
+
+`iproute2`라는 패키지를 설치하면 사용할 수 있다고 한다
+
+`iproute2`라는 패키지는 리눅스에서 네트워크 관련 작업를 수행하는 역할을 한다
+
+```bash

+그래서 homebrew를 이용해 iproute2mac 패키지를 설치해 주었다

+To rerun under ARM use:
+arch -arm64 brew install ...
+To install under x86_64, install Homebrew into /usr/local

+이런 에러가 떠서… ARM 아키텍처로 터미널을 실행한 뒤 설치해 주었다
