The network is designed using the network address 200.100.100.0 which then is sub-netted using 3-bits from the host address space.

The following addresses are given to solve the fill in the blanks in Questions 41 thru 47.

IP Address of node A: 200.100.100.66

Subnet Mask: 255.255.255.224

DNS IP address: 200.100.100.99

Ethernet address of node A: Mac_A

Ethernet address of Router R1 at IP address 200.100.100.65: MAC_R1

Ethernet address of Router R2 at IP address 200.100.100.34: MAC_R2

Node A is requesting a web page from the web server presented in the diagram using the following

URL: http://www.gap.com

Fill in the blanks with the correct information to show TCP/IP protocols logic processed as per the given network diagram, so that the Node A can then successfully send the request to the web server after having resolved the URL to its corresponding IP address.

1. Node A has to resolve the domain name __________ using _______ server.

2. Node A generates a broadcast using __________ protocol to resolve R1’s IP address to its Ethernet address.

3.Node A then determines that NR Query must be forwarded to a router__________ at an interface with IP address___________, and the MAC address____________.

4. Router______________ then forwards the IP packet to router_________________ at an interface with IP address___________________, and the MAC address_______________.

5.Router ________________ then forwards the IP packet to the DNS server at the port________________, and the protocol________________.

6. The DNS server resolves the name query and returns resolved IP address ________________.

7.Node A can now complete the web pages request with the followings parameters:

Source TCP port number greater than: ___________________.

Destination port number: ________________________.

Source IP Address: ________________________.

Destination IP address: ____________________.

Source MAC Address: _________________________.

Destination MAC address:__________________________
