You haven't indicated what operating system you are using. For windows, using the 'ipconfig /all' command will show you what the DHCP server address is.
DHCPInform is a DHCP message used by DHCP clients to obtain DHCP options. While PPP remote access clients do not use DHCP to obtain IP addresses for the remote access connection, Windows 2000 and Windows 98 remote access clients use the DHCPInform message to obtain DNS server IP addresses, WINS server IP addresses, and a DNS domain name. The DHCPInform message is sent after the IPCP negotiation is concluded. The DHCPInform message received by the remote access server is then forwarded to a DHCP server. The remote access server forwards DHCPInform messages only if it has been configured with the DHCP Relay Agent..
DHCP server must be assigned a static IP address...On a Windows computer you can find out the IP address of the DHCP server that assigned your current IP address by opening a command prompt and typing "ipconfig /all".

DHCP Server can be a standalone server
Automatic Private IP Addressing (APIPA) is a feature of Windows-based operating systems (included in Windows 98, ME, 2000, and XP) that enables a computer to automatically assign itself an IP address when there is no Dynamic Host Configuration Protocol (DHCP) server available to perform that function. APIPA serves as a DHCP server failover mechanism and makes it easier to configure and support small local area networks (LANs).
ipconfig /renew if you're on windows
yes DHCP require the authorization of the dhcp server before IP addresses can be allocated because until we authorize DHCP server the network does not know who is the dhcp server for the subnet. The DHCP server broadcasts the information to all.
According to Microsoft:How to use automatic TCP/IP addressing without a DHCP server"A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance."For more information, see Related Links, below.
