 # showipaddress
-one binary solution to see all IP addresses on a linux machine
+
+
+## What?
+one binary solution to see all IP addresses for:
+
+* linux
+* windows
+* osx
+* bsd
+* arm64
+
+## How?
+
+download a release version or build your own with make
+
+```make all```
+
+
+simply run the binary produced
+
+sample output
