Deep dives into the protocols that power the internet.
TLS 1.3 is faster and more secure than TLS 1.2. Learn how the handshake was simplified, why RSA key exchange was removed, and how 0-RTT resumption works.
Facebook and Netflix claim IPv6 is 10-15% faster. We explain the technical reasons why removing NAT improves header processing and routing efficiency.
Run code at the edge, milliseconds from users. Compare Cloudflare Workers, Lambda@Edge, and Fastly Compute for serverless edge applications.
The world is running out of IPv4 addresses, but IPv6 adoption is slow. These transition technologies bridge the gap, letting IPv6 and IPv4 networks communicate.
Traceroute reveals the path your packets take across the internet. Learn how TTL manipulation works, why some hops show asterisks, and how to interpret AS paths for network debugging.
Video calls work through firewalls and NAT? WebRTC uses ICE, STUN, and TURN to punch holes in NAT and establish direct peer connections. Here is the complete technical breakdown.
