Proxy-server. How to make Steam bypass the proxy server.

[Брэнт]

I use proxy to get access to youtube. But steam aint work while proxy on.
I turn it on manually: Settings > Network & Internet > Proxy. And there is the exception list - all adresses writen in list will bypass proxy.

What i need to write in the exception list so i could use steam and zombifie myself in youtube at the same time?
