My "wire" / not yours\n\n\n\nI am looking for a way to secure DHCP. I have a network with all the\nfrills; DCHP, DNS, DOMAIN, Etc.\n\n\n\nI know how to use DHCP to the point of settings address ranges etc.. What I\nwould like to do is make it so that machines that aren't know to me. Such as\nusers laptops and WiFi devices aren't allowed access to the network and\nobtain an IP address unless I am notified and allow it.\n\n\n\nRight now on the 2nd floor someone could just "jack" in and poof. they have\nan IP.\n\n\n\nAnother thing I could do is this . I would set ISA to now allow network\naccess outside of the network (somehow) if they don't have a domain\nuser-id/password.\n\n\n\nThis being all said. Why would I want to even get an IP. If I don't know\nyou I don't know you . then again I don't know you why do I want you on my\nwire!
