This DNS server knows all the devices in the internal domain and can assign them the respective name. For outgoing requests — in other words, requests to the Internet — this internal DNS server can contact one or more external DNS servers and answer the requests in this way via the DNS network.

For example, once a DHCP server has assigned an IP address to a client which has submitted a request, it can also communicate this information directly to a DNS server. In another version, the client itself can also communicate this information to the DNS server.

The latter system is employed by Windows clientsfor example.

It includes information such as IP address and subnet mask of the computer, IP address of the router and IP address of the name server. The DHCP contains two components i.

The protocol is used to transport host-specific configuration parameters from a DHCP server to the host and a mechanism is used to assign network addresses among the hosts. When a host gets active, it contacts to the DHCP server and request address information.

The DHCP server chooses an address and allocates it to the host.

But these addresses are leased for a particular period after the expiration of lease the host can contacts to the DHCP server and requests to extend the lease. This lease mechanism is very useful for finding non-working moved or switched off hosts.

In the given cases hosts do not hold on to the addresses and addresses are returned to the address pool by the DHCP server which can be reallocated as necessary.
