Hello y'all:<br>The greatest Venezuela's ISP (CANTV) is evaluating to use the ISC's DHCP server to offer IP's to their suscribers. Right now, CANTV has almost 2.000.000 of suscribers, and I need to find someone with major experience in such a big instalations with ISC's DHCP.
<br>I am waiting for the last DHCP server stats, to give you a better idea of the loading process.<br><br><br><div class="gmail_quote">On Jan 19, 2008 6:10 AM, Simon Hobson <<a href="mailto:email@example.com">firstname.lastname@example.org
