Instructed by Bogdan Stashchuk 14.5 hours on-demand video & 2 articles
What you’ll learn
-
How Computer Network operates on different layers of the What are TCP/IP and OSI model
-
Logical and hardware addressing of the devices (IP addresses and MAC addresses)
-
IP addressing, Network masks, Subnets and Subnetting
-
How Switches perform switching decisions and build MAC address tables
-
How Routers build routing tables and which type of routes exist and how routers utilise Routing tables to route packets
-
How packets are transferred end-to-end via Switches, Routers and how network headers (Ethernet and IP) change during this transmission
-
Understand purpose and differences of the TCP and UDP protocols
-
Learn how DNS registry is built and which types of the DNS Nameservers exists and what are their responsibilities
-
Learn difference between private and public IP addresses, concerns related to them and need for NAT – Network Address Translation
-
Understand differences between link-state and distance-vector routing protocols and learn what is BGP – core routing protocol in the Internet
In practice sections you will perform multiple practice Networking activities:
- Install Wireshark and use it for analysis of the networking protocols
- Analyse Ethernet headers
- Understand how DCHP requests and responses help to get IP address assigned to the host

- Practice subnetting
- Examine ARP cache
- Explore IP, DHCP and NAT settings of the Wireless Router
- Use nslookup utility to perform DNS and reverse DNS lookups with queries for different types of the DNS records (A, AAAA, TXT, MX)
- Analyse TCP and UDP headers
- Check information about domain names, public IP addresses and ASNs (Autonomous System Numbers)
