without a dns setting, you can't browse the internet without putting in ip addresses, it has nothing to do with getting your ip address assigned via dhcp. there is just no place to specify your dns servers when you have a static ip. when you set it to dhcp, it assignes you an ip address, along with a subnet, default gateway and dns. when you set it manually, you can only set ip, subnet, and gateway. there's no place for dns...thats the problem
