Несколько машин в той же сети, получающей тот же IP, арендуют через DHCP

Я создаю 18,04 машин на VMware с двумя сетевыми интерфейсами. 192.168 и 10.100.

У меня есть человечность vm настроенный как dhcp сервер для обеих сетей - у меня есть серьезная проблема с DHCP, потому что различные машины - с различными MAC-адресами получают тот же IP-адрес.

В списке ниже Вас видят, что 192.168.1.206 был выпущен к 4 машинам!

Это особенно странно, потому что DHCP на маршрутизаторе получал подобную проблему. Я никогда не видел ничего как это прежде.

Ta,

Andrew
