What else can I help you with?
When configuring a network connection to the Internet you might need to enter the IP address of the computer the DNS server the subnet mask and the default gateway. Of these four items which are us?
Of the four items—IP address, DNS server, subnet mask, and default gateway—only the IP address is specific to your computer. The DNS server translates domain names into IP addresses, the subnet mask defines the network and host portion of the IP address, and the default gateway is the device that routes traffic from your local network to the Internet.
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 is specified by the network number in an IP address?
The network number in an IP address is that portion of the IP address that matches the subnet mask. For instance, if the IP address is 10.11.12.13 and the subnet mask is 255.255.0.0, then the network number is 10.11.0.0. If the subnet mask is 255.255.255.0, then the network number is 10.11.12.0. The network layer (layer 2 in the OSI model) in the TCP/IP protocol stack uses the network number to determine if the destination address is directly reachable, or if the frame needs to be routed through the default gateway.

Which part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
Which information is used by the router to determine the path between the source and destination?
network portion of ip address
Which information is used by the router to determine the path between the source and destination hosts?
network portion of ip address
Which portion of a receiving machines ip address 172.16.3.0 16 in this instance would a router use to determine the destination network?
172.16.0.0
What is a public ip different then network id?
An "ip address" is a complete source or destination address that has a network id portion and a client or host portion. The network id is just a piece of the IP address. So, a public ip is an IP address that can be routed, whereas the network id is just a part of the public ip. They aren't different; the network id is part of the ip address.
What portion of the IP address does the prefix represent?
It represents the network portion
What part of an IPv4 address specifies a particular network interface on the network?
The host portion specifies the particular network interface's address. The network portion specifies the network address.
