binding ips to accounts

[HypoMaster]

hi ya,

recently ive had a problems with people binding to ips that are not issued then, has any one written a script where i can the server reads for example /etc/ip.conf before binding any user files, and in /etc/ip.conf ude have eg ricky:66.66.66.21 and ricky can only bind to that or vhost:66.66.66.1 every one cause use as a vhost only but wont allow any think to bind to it,

Cheers

Ricky
