I need to have a deeper understanding of network fundamentals, specially in the cloud.
Topics
Some topics I’m intersted in studying more deeply:
- CIDR notation — Standard IP addressing (RFC 1519)
- Subnets & subnet masks — Core TCP/IP concept
- Public vs Private IP ranges — RFC 1918 private addresses (10.x, 172.16.x, 192.168.x)
- Routing & route tables — How packets find their destination
- Default gateway/route — Where to send traffic when no specific rule matches
- NAT (Network Address Translation) — Allowing private IPs to access the internet
- DNS resolution — Translating hostnames to IPs
- High availability zones — Distributing resources across physical locations
Study path
Learn these first:
- OSI model layers 2-4
- TCP/IP fundamentals
- Basic routing
The cloud-specific resources are just managed implementations of these universal concepts.
