Как найти мой локальный IP-адрес, предоставленный мне моим маршрутизатором?

Question 1

Я знаю, что могу получить свой локальный IP-адрес, который мне дал мой маршрутизатор / коммутатор через графический интерфейс через:

Настройки сети> Нажатие на значок шестеренки в моем соединении> Детали

GUI view to see the local IP address

Я вижу, что мой локальный адрес IPv4 - 192.168.0.33 .

Теперь я хочу получить эту информацию через скрипт, но команды вроде ifconfig или ip addr show не помогают, так как спамят много ненужной информации, особенно когда у меня установлено и работает множество докерских сетей:

Информация там скрывается:

        inet 192.168.0.33  netmask 255.255.255.0  broadcast 192.168.0.255

, но я не знаю, как правильно отфильтровать ее. Что является более кратким способом получить мой локальный IP-адрес, данный мне маршрутизатором / коммутатором?

Я хочу следующий вывод:

$ find-my-local-ip
192.168.0.33

Question 2

Автор Бруно Броноски из Unix & Linux :

 ip route get 8.8.8.8 | sed -n '/src/{s/.*src *\([^ ]*\).*/\1/p;q}'

делает то, что я хочу.
