The type of structure DNS uses is hierarchical.
When you type a website into your web browser, like, for instance, google.com your computer does not know the IP address. Therefore, it attempts to connect to the internet to make an ARP (address resolution protocol) request. The request is forwarded onto the local DNS (domain name server). The DNS, if it has the IP address, forwards the information back to you. If it does not have the information, it requests the information from one of the thirteen root DNS servers on the internet.

The network layer (Internet Layer in TCP/IP model) is the second layer of the TCP/IP model. IP (Internet Protocol), ARP (Address Resolution Protocol), RARP (Reverse Address Resolution Protocol), ICMP (Internet Control Message Protocol) and IGMP (Internet Group Management Protocol) are the protocols at this layer. http://www.omnisecu.com/tcpip/internet-layer.htm

Domain Name System (DNS) and Address Resolution Protocol (ARP) are used for address resolution. Internet Control Message Protocol (ICMP) is also used to determine if an address is reachable.DNS maps a hostname to an IP address and ARP is used to map an address to a physical network hardware address.ICMP messages are typically generated in response to network errors for diagnostics and route tracing but are used to ping an address.

An ñARPî or Address Resolution Protocol is a protocol that is used in telecommunications for a resolution of network layer addresses into link layer addresses, which is vital in multiple access networks. It is also the name of the program that is used when manipulating addresses in most operating systems. The Address Resolution Protocol is used to convert an IP address to a physical address such as an Ethernet Address.
ARP stands for Address resolution Protocol.......it is the method for finding a host's link layer (hardware) address when only its Internet Layer (IP) or some other Network Layer address is knowns the method for finding a host's link layer (hardware) address when only its Internet Layer (IP) or some other Network Layer address is known.

Destination NAT forwards requests for network resources using a public IP address to a private IP Address Dynamic NAT can dynamically assign public ip addresses to internal hosts making requests from resources outside the private network Source NAT implementations change the source address on outgoing connections from a private IP address to a public address.
