Section B
1.
a) Compare ALL your results from section 1 (1) to that of two any fellow students. Make sure the
comparison is done block by block/octet by octet.
Own Info Student 2 Student 3
IP Address …………………………….. ………………………………. …………………….
MAC Address ……………………………… ………………………………. …………………….
Subnet mask ……………………………….. ………………………………. …………………….
Default gateway ……………………………. ………………………………. …………………….
DHCP server ………………………………. ………………………………. …………………….
DNS server …………………………………. ………………………………. …………………….
b) Are the results the same? If no, what are the differences? (NB: ONLY compare results with students
connected to the same network e.g wireless LAN VS wireless LAN)
……………………………………………………………………………………………………………
