Is there some way to use both DHCP-assigned and custom DNS servers? My school's network seems to require use of the DHCP-assigned DNS servers to access anything outside the network (no, I'm not entirely certain what they've done with their router configuration to accomplish this); however, I do not want to remove my custom DNS servers (OpenDNS and a couple others). Therefore, I would like to have the DHCP-assigned DNS servers added either to the top or to the bottom of my DNS server list. Does anyone know how to accomplish this?
