[sudo-discuss] network static IP and questions

i'm reading the wiki page but i don't see how to set up a static IP address https://sudoroom.org/wiki/Network i see that static IP addresses are below .42.50 can i just set up something to take that address and it will be fine? I don't have to set it up somewhere else? also.. i noticed that none of the stuff in the internet factory upstairs is labeled - it's just wires going here and there that you have to follow. is anyone planning on labeling that stuff? thanks -jake
