we need to have a IP address for the purpose of connectivity and that IP address should be unique to due increase in the usage the exhaustion of IP address in IPv4 has occurred. IPv4 can be utilized for the interface of many advanced gadgets on the internet it can be utilized to unite the combine the computer based gagjets with the system.In the year February 2011 each organization is responsible for assigning their own IP addreses and

37) DHCP ________ are configurable parameters that determine which subnets the DHCP server will serve.

Scope: A range of IP addresses those are available to be leased to DHCP clients by the DHCP Server service.

DHCP (Dynamic Host Control Protocol): Stand alone network service used to assign the ip address and other related configuration automatically.

The Dynamic Host Control Protocol automatically assigns IP addresses to hosts on a network as they request them. DHCP packets also include information like DNS server addresses, domain names, and default gateways.

as a device in its domain and sends the packet to the host or pushes the packet to the next

Each campus will have a DHCP server to hand out ip addresses to nodes on the Curriculum network.

The attacking VM uses the stored ARP cache to re-direct packets from the client VM, to an attack machine, and then forward to the host, thus the attacker machine can see all traffic between client and host. First the target MAC address is established, and then the ARP Poison protocol poisons the cache of the client by forcing a cache update with the path re-routed so that the attacker machine forwards traffic to and from host and client.

Ans: Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers configured for a given network.

As for the functions, bridging devices inspects incoming network data whether to forward to the end user or to discard it.

Remember the internet works with ACL or access control list, allowing for the possible for a person to reach Google without being a part of the same subnet. There is a common method UDP host punching. UDP hole punching is a commonly used technique employed in network address translator (NAT) applications for maintaining User Datagram Protocol (UDP) packet streams that traverse the NAT. NAT traversal techniques are typically required for client-to-client networking applications on the Internet involving hosts connected in private networks, especially in peer-to-peer, Direct Client-to-Client (DCC) and Voice over Internet Protocol (VoIP) deployments. UDP hole punching establishes connectivity between two hosts communicating across one or more network address translators. Typically, an application, when it sets up direct communications between two or more communicating hosts choosing to use a third-party host on the public transit network by using a UDP port. Usually normal communications traffic or when there is no significant traffic keep-alive packet traffic usually consisting of empty UDP packets ore packets with minimal non-intrusive content enable once port state keep the port states open. A common example of programs which use UDP hole punching consist of Team

The DHCP clients request an IP address and other network settings from the DHCP server on the network. The DHCP server in turn leases the client an IP address within a given range or

Furthermore, by applying a display filter in Wireshark to examine 192.168.1.30, a device on the internal network, we can see that 192 DNS packets originated from this device (figure 3).
