Find out as many networks of IT-department respectively CNAP-network as possible. These are later used in Lab 3!
Please use the CIDR-notation 192.168.1.0 /24 with both the Network-address ass well as the subnet-mask in slash-format. Do not document IP-addresses like 192.168.1.1
This is a template how the resulting report-document should look like. Example only: (wrong addresses below, please change :-) )
FILL IN THE TEMPLATE AFTERYOU HAVE FINISHED THIS LAB, not now
A/ Give an example of a “Network” and an example of a computers "IP-Address" so Robert understands the that you understand the difference
B/ Networks of CISCO NETWORKING ACADEMY PROGRAM (CNAP)
23.34.36.0 /24 (Might be internal servers only) 23.40.12.128 /25 (Could be a compute farm)
10.1.33.0 /24 (Probably internal web server)
C/ Networks of the IT-DEPARTMENT (Swe: IT avdelningen)
194.1.2.128 /25 (Might be servers reachable from the internet) 194.33.12.0 /24 (Probably internal servers for Windows Infrastructure like DNS, AD, SMB/CIFS, …)
172.16.16.0 /24 (Could be the printers and the printqueue server)
D/ Networks of trollhattan.se (The city council, schools, etc)
…
E/ My best dig … AXFR (at home: watch Youtube - Zone Transfer Tutorial) <lines delete for clarity> wormhole 1D IN A 192.249.249.1 1D IN A 192.253.253.1 wh249 1D IN A 192.249.249.1 robocop 1D IN A 192.249.249.2 <lines deleted for clarity>
F/ The most compromising information I found (Picture or Text)
A/ Walk around to different computer lab rooms, and ask students what the IP-address is of their IT-departments managed computers (Ordinary PC's in Computer Rooms, not laptops)
B/ All students of the course Internettjänster (INT202 on Canvas) have the password to Netbox where all CNAP-network IPs are documented. What is the Username/Password for Netbox? Can you access it? Can you find a friend of a friend that can access it?
