On a Cisco router x IP lists check source packet addresses while y IP access lists check for both source and destination packet addresses?
x -> standard y -> extended
What is the role of the address field in a packet travelling through a datagram?
There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
What is the information contained in the Ip header?
The source and destination IP addresses
What is destination address?
IP addresses are used to deliver packets of data across a network and have what is termed end-to-end significance. This means that the source and destination IP address remains constant as the packet traverses a network.In simple terms again, Destination IP address is the receiver of information
Where are ports recorded in an ip based packet?
It's recorded at the top of the IP packet header. 16 bit source and destination port.
What is delivery report of IP?
The delivery of Packet byDestination Computerin TCP\IP stack is reported by sending Acknowledgement to the Source Computerfor the received Packet by Destination Computer.
Differences between arp packet transmission and ip packet transmission?
an arp (address resolution protocol) comes into picture when we have the ip address of our destination but we dont know the mac address of our destination.Normally when we open a web site this is the process which takes place.IP packet transmission comes after arp when the destination mac address is obtained after arp request.so an ip packet contains both source & destination IP & mac addr.
What protocol is responsible for resolving ip addresses to mac addresses for source hosts that knows ip addresses of the destination host but not the mac address?
ARP, or Address Resolution Protocol, defined by RFC 826.
Which portion if the destination IP address is used as a packet is routed through the Internet?
Which portion of the destination IP address is used as a packet is routed through the Internet?
Which portion of the packet does a router use to forward the packet to the destination?
The Destination Address (Layer 2 or Layer 3)
What Usage of no ip source-route?
I think ip source-route and policy routing very often get confused, but they are two very distinct things. Policy routing is a way of specifying routes to depend on various parameters, including perhaps the source IP address of a packet. It is a local policy applied at a router. ip source-route is something entirely different. It is a feature where the originator of an IP packet specifies, in that packet, which routers the packet must go through to reach its destination. The path is tagged onto the options field of the IP packet. The feature is very dangerous, and most NetAdmins disable it. I think the confusion comes about because of the words "source" and "route".
Which part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
