You must want to HELP the little shits then.
Think of this for a second. Right now he has maybe 4-5 different servers
people are putting the IP numbers on. Once you move all those servers onto

the gateway router onto their systems, then the entire subnet that ALL the
servers are on becomes inaccessible.
