Things dont get supplied automatacly. If you have a DHCP Server, you need to configure the scope by wich he will be assigning IP addresses. Configuring a DHCP Server Scope options is not saying it will give IPs from 10.0.0.x - 10.0.0.y. You can, and should, define on the Scope Options, the DNS server, NetBIOS, Gateway, etc etc. You have allot of options. If you cant "get out", thats a ottaly different issue. Try ping something outside your network/subnet (using IP and FQDN). If IP works and FQDN doesnt, you have a DNS problem. You need to make a drawing on paint or something to help us understand your network.
