Hello all. We have a small - Windows SBS 2011 Standard - network at a church using most of the 240 IP scope I've set up, internally. Currently at 192.168.0.1 (router IP) and 192.168.0.3 being server and DNS. We have several really large events here on campus - 1500 to 2500 attendees every year, with the majority of those attendees hitting the internet during the event. Obviously I'm running out of IP's. What is the easiest way for me to increase available IP's? I have all printers setup with reservations via MAC on the server. Everything thing else other than the router, is all DHCP.
