Thanks Frank, Mattew and Mike. Unfortunately, I use the DHCP server which is provided by my ISP, so I don't have access to it. Meanwhile, I don't want to use my school's DNS server though, since using ISP's DNS server seems a little bit faster. Maybe I will just go ahead and put some code in my rc.local.
