Hey re, fellow sysadmin or dev! Are you stuck trying to track down those elusive Docker container IP addresses? Well, fear not! I've got you covered with a smorgasbord of methods to find 'em faster than you can say "ping!" Let's dive into nitty-gritty of this Docker networking biz.

docker network inspect
