Lab Worksheet – What’s in the Digital World?
Cyber School 21/08/2025
Lesson: Whatโs in a Digital World?
Focus: IP Lookup & WHOIS Investigation
Tools: Browser-based, no installation needed
Time: ~25โ30 minutes
Goal: Learn how to trace digital identities using IP and domain lookup tools.
๐ฏ Lab Objectives
By the end of this lab, students will:
- Understand what an IP address is and how it relates to websites
- Use public lookup tools to find information about an IP or domain
- Read WHOIS records to identify the owner, registrar, and technical details
- Reflect on how digital traces are stored and revealed online
๐ Step 1: What Is an IP Address?
๐ฌ IP = Internet Protocol address โ a unique number assigned to every device on the internet.
๐ Go to this website to see your own IP address:
๐ https://whatismyipaddress.com
๐ Write down your IP (v4 or v6), location, and ISP provider.
๐ Step 2: Investigate a Website (Using IP Lookup)
You will now investigate the digital footprint of a real website.
Website to analyze:
๐ต๏ธ https://cyber-school.co.il
- Open: https://iplocation.net
- Type the domain above and press search
- View the server IP and its location
๐ Answer:
- What is the IP address of the site?
- Where is the server located?
- What hosting company or cloud service is used?
๐งพ Step 3: Run a WHOIS Lookup
WHOIS is a public record system that stores ownership details for websites and domains.
- Go to: https://who.is
- Enter:
cyber-school.co.il - Scroll through the WHOIS record
๐ Answer:
- Who is the registrar?
- When was the domain created?
- When does it expire?
- Is the contact info public or hidden?
โ ๏ธ Bonus Task (Advanced)
Try looking up another domain:openai.com or google.com
Find and compare:
- Server country
- Hosting provider
- WHOIS privacy settings
๐ก Reflection Questions
- What surprised you about what was publicly available?
- Why do some domains hide their WHOIS info?
- How could this data be useful to cybersecurity professionals?
- What does this teach you about your own digital identity?
๐ก๏ธ Cyber Safety Reminder
- IP and domain lookup tools are legal and public โ but use them ethically.
- Just because something is visible online doesnโt mean you should misuse it.
