Today's lesson is...

What NOT to do when setting up a new server in a data center:

1) Assign the server a static IP on the subnet ending in .1
2) Assign a totally bogus gateway
3) Continually reboot the new server, not understanding why it won't work

Today, a member of our server group did all that he shouldn't have. As luck would have it, the .1 IP just so happened to be a distribution core. It's always fun seeing server after server drop off the map....

Ah, yeah, back in the good 'ole days everything went dead early one morning. Web, email, DNS, everything. Turns out of the Unix server guys did #1 & 2. He didn't reboot continually. Once people got in a tizzy, he realized the problem and pulled the network plug. He normally came into work no earlier than 11 AM, but his boss wanted him coming in at 8AM "like all the other staff."

I'm not understanding why an address ending in .1 is bad.

#2 and #3, I get, but I have machines that are network address +1. Is it just that that address was already used on the subnet?
