· routers, like every other device on the network, send and receive data on the network, and build ARP tables that map IP addresses to MAC addresses · if the source resides on a network that has a different network number than the desired destination, and if the source does not know the MAC address of the destination, it will have to use the router as a default gateway for its data to reach the destination · routed protocols direct user traffic, whereas routing protocols work between routers to maintain path tables · network discovery for distance-vector routing involves exchange of routing tables The next chapter discusses the functions of the transport layer.

Routing tables are either created statically, or by the systems administrator configuring the system, using the startup or configuration fiels, to used a pre-defined, unchanging route.dynamically. · There are protocols, part of TCP/IP, that will dynamically modify the routing table in response to events. · Adding a host to the network requires obtaining, installing and configuring the necessary network hardware, gather the required information including IP address and hostname of the new host, the gateway and the name server, the network address and the subnet mask, modify the appropriate configuration and startup files with that information, make sure the new host has an entry in the domain name service, test the connection.
b. IDS- Intrusion Detection System- 2 types: Active and Passive c. NAT- Network Address Translation- Appends to your logical port. Protects internal hosts. Used with proxy servers. Translates internal IP to Real IP. Uses unique port table.
On the other hand IP is internet protocol and this protocol makes sure that the data packets know where to go. It makes sure that the data packet knows the route to the receiver of the data packet. IP address is stuck on the data packet it is like a label that has the information of where the data packet has to go and the information of the sender. In order for communication to take place the information has to go through four layers and it all happens in split second. Explain each of the application layers and the PDU’s within them There are four layers application, transport, internet and network access.
Having a static IP address allows for clients to find the servers. A DHCP server responds to a client PC when the PC broadcasts a dynamic host configuration protocol message to all of the nearby hosts. The Simple Network Management Protocol (SNMP) IPv6 Management
The router sets up the network interface and the routes that it will run. The network and subnet for each interface on the routes are then added to the router. All non local data is sent along a simple static default route to the cable company. If a web page is requested the router receives it, then checks the destination IP address. The bits in this IP address are used as a hash point for the correct route.
• Both are used for different purposes normally. SSH is used to create a secure connection over a network and SSL is used to transfer data securely by encryption techniques and use of certificates. So it is the purpose that decides which one is better.

TCP/IP Name Affiliation Date TCP/IP Introduction TCP stands for Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different vendors. By use of TCP/IP, several computers on small network in a department can use these protocols in conjunction with other protocols on a single LAN.
3. In the IP address box this is where you will want to fill in the place to forward the ports to at least on the linksys you can do this by individual IP address. Put the IP Address of the machine on your LAN that you are using Direct Connect on. If your are running DC on multiple machines you may have to repeat steps 1-3 for each IP on your LAN running DC. Click Apply restart DC and you should now be able to use DC and search multiple hubs behind your route/firewall without any problems.
The interface ID is created using Modified EUI-64 Format Interface Identifiers algorithm, which takes the 48 bit long MAC address of the Ethernet card and expands it to the 64 bits needed for the interface ID. This has a disadvantage. An interface will always have the same interface ID independent of what site it resides or what prefix it currently uses and thus node becomes traceable. IPv6 addresses are of three types: 1. Unicast- it uniquely identifies a singl... ... middle of paper ... ...le, to resolve the link-layer address via multicast.
